ALMA OBSERVATORY

Planet formation may start during the embedded phase of star formation. In this scenario, the chemistry of embedded disks may directly determine the chemical composition of the forming planets. In recent years, observations discover several embedded protostars that have developed complex chemistry at the disk-forming region. However, only a few observations attempt to constrain the occurrence of complex molecules at embedded protostars and their relationships to star formation processes. I will present the first result of the Perseus ALMA Chemistry Survey (PEACHES), which aims to unbiasedly survey the chemistry toward 47 embedded protostars with a spatial resolution comparable to the size of disk-forming region. In PEACHES, we identify a variety of molecules and their isotopologues, including CCH, c-C3H2, SO, SO2, CH3OH, CH3CN, CH3OCHO, CH3OCH3, and C2H5OH. I will discuss the detection statistics of these molecules with respect to the physical properties of these protostars, such as their evolutionary stages and disk properties. I will also discuss the correlations of these complex molecules and the comparison with the chemistry of the protostars at other regions and environments. The occurrence rate of different complex molecules learned from the PEACHES survey will provide a primer for constraining chemical evolution during the star formation. 5/27 (Wednesday) 14:20 - 15:20 R1203

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, have spotted a peculiar gas cloud that resulted from a confrontation between two stars. Find out more about this stellar fight in this ESOcast Light. The video is available in 4K UHD. The ESOcast Light is a series of short videos bringing you the wonders of the Universe in bite-sized pieces. The ESOcast Light episodes will not be replacing the standard, longer ESOcasts, but complement them with current astronomy news and images in ESO press releases.

April 25, 2019 Phillips Auditorium Sofia Ramstedt Uppsala U. Host: Rodolfo Montez Abstract: The deaths of stars are always preceded by more or less massive stellar winds. In the case of low- to intermediate mass stars, these winds are the means by which material from the stars is recycled in galaxies. Accurate measurements of the wind physical properties provide constraints for hydrodynamical models which study wind formation and evolution. Estimates of wind density and temperature also form the base for any further research into abundances of different elements, isotopes and molecules in the recycled material. Furthermore, to determine wind gas-to-dust mass ratios holds the key to investigations of extragalactic objects and the impact of these common stars across the Universe. We have lately performed detailed studies of the circumstellar envelopes (CSEs) around nearby (500 pc) stars on the Asymptotic Giant Branch (AGB) with ALMA. The properties of the wind which has created the CSE, can be derived by mapping the CO line emission. We started with a smaller sample of binary stars to investigate the formation and importance of circumstellar asymmetries and structure. To interpret the complex observations, several new analysis tools had to be assembled and tested. These tools are now put to use for the DEATHSTAR project in which we are mapping all nearby AGB stars starting in the southern sky. The goals are to provide the most accurate AGB wind properties to date, and to consistently determine the gas-to-dust mass ratios. I will present results and current status.

The English version is available on http://www.eso.org/public/videos/eso1312a/ This 16-minute video presents the history of ALMA from the origins of the project several decades ago to the recent first science results. Illustrated by dramatic helicopter footage, the movie takes you on a journey to the 5000-metre-high Chajnantor Plateau, where ALMA stands, in the unique environment of the Atacama Desert of Chile. The movie was released by ESO, with its international partners to mark the occasion of the inauguration of the Atacama Large Millimeter/submillimeter Array (ALMA) on 13 March 2013. ALMA — In Search of our Cosmic Origins tells the story of the project from its earliest beginnings, when Europe, North America and East Asia developed a common concept for a new, large telescope for millimetre and submillimetre wavelength observations to observe the coldest and most distant objects in the Universe. It also charts the search for the perfect location and the technical and logistical challenges posed by the building of such a massive infrastructure under extremely harsh conditions and in a remote place. The movie includes detailed shots of the complex and fascinating technology that ALMA depends on, and explains how the 66 antennas were installed on the high desert plain. It also provides insights into the exciting scientific developments that this, the most powerful telescope of its kind, will bring. These expectations are already being fulfilled by the first science results, obtained before the facilities were even complete.

This zoom video starts with a wide view of the Milky Way and ends with a close-up of the Abell 2597 cluster. Observations by ALMA and data from the MUSE spectrograph on ESO’s VLT have revealed a colossal fountain of molecular gas powered by a black hole in the brightest galaxy of the Abell 2597 cluster — the galactic cycle powering this vast cosmic fountain has never before been observed so clearly. The final shot is a composite image of the Abell 2597 galaxy cluster showing the fountain-like flow of gas powered by the supermassive black hole in the central galaxy. The yellow is ALMA data showing cold gas. The red is data from the MUSE instrument on ESO’s Very Large Telescope showing the hot hydrogen gas in the same region. The extend purple is the extended hot, ionized gas as imaged by the Chandra X-ray Observatory.

Animation of a star exploding into a supernova and fueling a gamma-ray burst. Astronomers caught the enduring "afterglow" of one of these cataclysmic explosions with both ALMA and the VLA for the first time. The rebound, or reverse shock, triggered by the GRB’s powerful jets slamming into surrounding debris, lasted thousands of times longer than expected, giving astronomers an unprecedented glimpse into the structure and dynamics of the jets.

ALMA has uncovered convincing evidence that three young planets are in orbit around the infant star HD 163296. Using a new planet-finding technique, astronomers have identified three discrete disturbances in the young star’s gas-filled disc: the strongest evidence yet that newly formed planets are in orbit there. These are considered the first planets discovered with ALMA. The video is available in 4K UHD.

Your home and the Universe have at least one thing in common: they can be very dusty places! When you get back after a very long vacation, it may happen that the windows in your home are so full of dust that you can’t see through them anymore. Surprisingly, astronomers have a similar problem!

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a surprising connection between a supermassive black hole and the galaxy where it resides. Powerful radio jets from the black hole – which normally suppress star formation – are stimulating the production of cold gas in the galaxy's extended halo of hot gas. This newly identified supply of cold, dense gas could eventually fuel future star birth as well as feed the black hole itself.

The most complex ground-based astronomy observatory in the world, the Atacama Large Millimeter/submillimeter Array (ALMA), has officially opened for astronomers. The first released image, from a telescope still under construction, reveals a view of the Universe that cannot be seen at all by visible-light and infrared telescopes. Thousands of scientists from around the world competed to be the first few researchers to explore some of the darkest, coldest, furthest, and most hidden secrets of the cosmos with this new astronomical tool.
