The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
Secular evolution and a non-evolving black hole to galaxy mass ratio in the last 7 Gyr
Mauricio Cisternas, Knud Jahnke, Angela Bongiorno +6
We present new constraints on the ratio of black hole (BH) mass to total galaxy stellar mass at 0.3<z<0.9 for a sample of 32 type-1 active galactic nuclei (AGNs) from the XMM-COSMO…
On R-W1 as A Diagnostic to Discover Obscured Active Galactic Nuclei in Wide-Area X-ray Surveys
Stephanie M. LaMassa, Francesca Civano, Marcella Brusa +18
Capitalizing on the all-sky coverage of {\it WISE}, and the 35\% and 50\% sky coverage from SDSS and Pan-STARRS, respectively, we explore the efficacy of (optical) - $m_{3.…
Quiescent times in gamma-ray bursts: II. Dormant periods in the central engine?
Enrico Ramirez-Ruiz, Andrea Merloni, Martin J. Rees
Within the framework of the internal-external shocks model for gamma-ray bursts, we study the various mechanisms that can give rise to quiescent times in the observed gamma-ray lig…
Quantifying Observational Projection Effects with a Simulation-based hot CGM model
Soumya Shreeram, Johan Comparat, Andrea Merloni +11
The hot phase of the circumgalactic medium (CGM) allows us to probe the inflow and outflow of gas within a galaxy, which is responsible for dictating the evolution of the galaxy. S…
SDSS-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Gail Zasowski, Hans-Walter Rix +47
SDSS-V will be an all-sky, multi-epoch spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way, trace the emergence of the chemical…
