21. Overview of the Local Volume Mapper Instrument

Tom Herbst

7/31/23, 3:30 PM

The Local Volume Mapper (LVM) survey employs four, 16-cm telescopes feeding 3 fiber-fed spectrographs at Las Campanas Observatory, with the goal of mapping the Galactic plane with 37” spatial resolution and R~4000 spectral resolution. One telescope hosts the science IFU, while two others observe adjacent fields to calibrate geocoronal emission. The fourth telescope measures bright stars to...

22. Spectroscopic Variability of Active Galaxies and Quasars 101

Jessie Runnoe

7/31/23, 3:42 PM

Active galactic nuclei (AGN), the visible result of supermassive black hole growth, are prevalent in many fields from galaxy evolution to gravitational wave astrophysics. However, our understanding of these objects has been limited because the primary emission regions surrounding the supermassive black hole, the accretion disk and broad-line region (BLR) that make up the central engine, cannot...

23. Changing-Look Quasars: Zooming in on X-ray/Optical Variability, Zooming out to the Big Picture

Qian Yang

7/31/23, 4:07 PM

'Changing-look quasars' (CLQs), discovered less than a decade ago, show dramatic, rapid changes in optical/UV continuum and broad line emission strength. CLQ transitions have been attributed to tidal disruption events, changes in intrinsic absorption or in accretion rate, but all these hypotheses suffer theoretical or empirical challenges. X-ray observations can clearly distinguish between...

24. Software 101

José Sánchez-Gallego

7/31/23, 4:19 PM

In this talk I will review recent software development in SDSS as part of our instrumentation, target selection, data analysis, and data archiving effort. I will highlight and demo key software that has been instrumental in getting SDSS-V on sky and taking data nightly. Finally, I will provide an overview of the collaboration policies and procedures for DevOps.
