Could We Detect Planets Around Dead Stars? | Jorge Cortés
We know of thousands of planets but precisely zero around white dwarfs. White dwarfs are not weird unusual objects but the inevitable fate of over 90% of the stars in our Universe - including the Sun! They're so small and faint that no telescope, even Kepler, has been able to find planets yet. But a new telescope - called LSST - might change all that. Jorge Cortés, a graduate student here at Columbia in the Cool Worlds Lab, tells us today about his new paper where he calculates how feasible it would be for LSST to pull off this last great planet detection trick which has evaded us to date! ► Jorge Cortés & David Kipping (2018), "On the detectability of transiting planets orbiting white dwarfs using LSST", MNRAS, submitted: https://arxiv.org/abs/1810.00776

Trusted CI Webinar: Security Program at LSST with Alex Withers
Originally recorded on June 25, 2018. The concept behind the Large Synoptic Survey Telescope (LSST) is simple: conduct a digital image-based survey over an enormous area of the sky and build an extensive astronomical catalogue over the course of ten years. LSST’s astronomical data is the ultimate deliverable to its users. This unique scientific computing environment presents many cyber security challenges. LSST has in place a cyber security program to facilitate its scientific mission: to protect its data access requirements and rights. We will discuss the beginnings of LSST’s cyber security program, adoption and experience with its risk management framework, existing and planned security operations at LSST sites, including the observatory site in Chile and the National Center for Supercomputing Operations (NCSA). This talk is presented by Alex Withers. Alex is a Senior Cybersecurity Engineer at the National Center for Supercomputing Applications (NCSA). He is the Information Security Officer for the Large Synoptic Survey Telescope (LSST). He is also a PI and co-PI for a number of NSF-funded cybersecurity projects.

Supermassive Black Hole Studies with the Large Synoptic Survey Telescope (LSST) - 2018
Supermassive Black Hole Studies with the Large Synoptic Survey Telescope (LSST) - 2018 Remote talk given by W. Niel Brandt (Penn State) to astronomers in the Brazilian Inter-institutional Laboratory for e-Astronomy (LIneA) on 2018 May 3. This talk represents some of the work done by the LSST Science Collaboration (SC) on Active Galactic Nuclei (AGNs). This talk has overlap with Brandt's talk of 2016 Dec 9 on AGN science with LSST (also on YouTube). However, this talk is more focused on the operations of the AGN SC and less focused on detailed science issues. Furthermore, it been updated to reflect new developments from 2016-2018. The talk outline is the following:
* Quick review of the LSST surveys
* The LSST AGN SC and its plans
* AGN selection with LSST and multiwavelength data
* Examples of exciting science investigations

LSST's Auxiliary Telescope
https://gallery.lsst.org/bp/#/folder/2689925/67271736 The Auxiliary Telescope wasn’t built from scratch; it’s an existing telescope that has been repurposed for its role in the LSST survey. Since being moved from its original location on nearby Kitt Peak in May, 2014, it’s been housed in the workshop at LSST’s Project Office in Tucson, AZ. Refurbishment work has included replacement of all the telescope’s electrical parts including the motors and the position encoders, which record the exact position of the telescope at any given time. Mechanically speaking, the telescope is largely unchanged. Its mirrors, which were removed while work was done, will be recoated and replaced once the telescope arrives on Cerro Pachón; they are currently in separate protective crates that will protect them during shipping.

KIPAC Public Lecture | The Fastest Eye on the Sky: The Large Synoptic Survey Telescope
What is the Universe made of? In modern cosmology only 4% of the universe is deeply understood, while the other 96%, Dark Energy and Dark Matter, remains a mystery. The Large Synoptic Survey Telescope (LSST), currently under construction, will observe billions of galaxies, billions of stars in our own galaxy the Milky Way, as well as millions of objects closer to home in the solar system. Every night over a ten year survey, LSST will observe much of the night sky, so that every portion of the sky will be imaged nearly a thousand times. In this talk, find out about the LSST observatory and this remarkable set of observations, and how we will be able to “see” the dark portion of our universe in unprecedented detail. Speaker: Aaron Roodman, KIPAC / SLAC National Accelerator Laboratory KIPAC is an independent laboratory of Stanford University. Initiated with a generous grant from Fred Kavli and The Kavli Foundation, the lab is support in part by Stanford University and in part by the United States Department of Energy as part of SLAC National Accelerator Laboratory.

A Day in the life of LSST Construction Part 3
This 11 minute slideshow includes 142 images and videos from a single day that show the breadth of work being done and the individuals responsible for construction of the LSST.
For one day, Thursday, September 14, 2017, everyone working on LSST was encouraged to submit an interesting picture representing their work in order to chronicle the LSST construction effort. We wanted to involve as many people in different parts of the project as possible, including contractors, so the many aspects of LSST construction were documented in addition to the people doing the work. Our goal was to show the full breadth of effort being applied on a typical day in LSST construction.
All together we received 142 submissions from 66 people, of A Day in the Life of LSST Construction Part 3.
LSST2017 Public Lecture: Building the Next Great Science Engine!
Presented by Victor Krabbendam & Chuck Claver
LSST Project Manager and Systems Scientist The Public is invited to attend a FREE Lecture, Thursday, August 17th, 7pm, at the Westin La Paloma Canyon Ballrooms, 3800 E. Sunrise Drive, Tucson, AZ. Project Manager Victor Krabbendam and Astronomer Chuck Claver will describe the revolutionary Large Synoptic Survey Telescope (LSST) from its motivation and early design to science operations which start in 2022. Currently under construction in Chile, LSST will survey the entire visible southern sky every few days for a decade – the widest, fastest and deepest view of the night sky ever observed. LSST’s vast archive of data will dramatically advance our knowledge of the dark energy and dark matter that make up 95 percent of the universe, as well as galaxy formation and potentially hazardous asteroids. LSST’s design takes advantage of technology breakthroughs in mirror construction, database technology, and camera sensor fabrication. LSST data will be available not only to professional scientists, but also to the public, including students and people involved in “citizen science” projects. Slides available:

LSST2017 Plenary: Welcome, Meeting Themes, Status
Monday 08/14/17 3:30 - 5:00pm
Welcome, Meeting Themes, Status The Project - Science Community interface - How can we support each other Two-way information flow between the LSST Project and the Science Community is critical for the community to prepare for LSST Operations, and for the LSST Project to buld a system that will maximize its science output. However, identifying the subject areas and processes that will generate the most effective and efficient interactions between the LSST Project and the Science Community has been a longstanding challenge. In this session, we will tackle this issue through a structured discussion. This discussion will be centered on recent use cases, for example lessons learned on Workflow Engine (i.e. running the Stack on different computing architecture), analysis of simulated/real images, input into commissioning and the observing strategy.

LSST2017 Plenary: LSST-WFIRST Connection; Simulated Observing Strategies/Cadence Optimization
Plenary: LSST-WFIRST Connection; Simulated Observing Strategies/Cadence Optimization Tuesday 08/15/17 9:00am - 10:30am
The LSST-WFIRST Connection
In an era following the launch of JWST, the "New Worlds, New Horizons" Astronomy and Astrophysics 2010 Decadal Survey outlined a vision for the US to usher in a new era of "Big Data Astrophysics". The pillars of this program are two incredibly complementary survey telescopes, LSST on the ground and WFIRST in space. While each of these programs stand on their own merits, it is broadly recognized that the whole is greater than the sum of the parts (e.g., Jain et al. 2015, arXiv:1501.07897). In this presentation, I'll introduce the complementarity of these amazing programs and specifically discuss the ways that strategic use of WFIRST can enhance the scientific return from LSST as outlined in the newly released LSST Cadence white paper. WFIRST offers a 0.28 sq deg field of view (100x HST’s visible cameras) with 0.1 arcsec pixels, and point-source sensitivities of up to 28th ABmag in 1 hour of integration (across 0.6 to 2.0 micron wavelengths). Focusing on broad astrophysics, the presentation will include topics stretching from Solar System science goals, exoplanets, stellar and galactic astrophysics, and cosmology, as well as unique opportunities through deep drilling fields and special programs. The goal of the presentation is to spark coordinated conversations between LSST and WFIRST science teams and advisory bodies to maximize the joint return from both programs. Simulated Observing Strategies and Cadence Optimization This session will provide an overview of the state of LSST Observing Strategy simulations, community analysis of these simulations, and the planned timeline and process for continuing community input. This will include a presentation of plans to solicit community white papers on Deep Drilling Fields and Mini-Surveys. Other possible topics for discussion include rolling cadence implementation, survey uniformity, simulations of survey conditions, and optimization algorithms. This session will include a presentation by Zeljko Ivezic, and the opportunity for discussion. Slides available:
