The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
The paper describes the twentieth data release (DR20) of the Sloan Digital Sky Survey, providing over 3 million new optical spectra from the SDSS‑V Milky Way, Black Hole, and Local…
The Age-Thickness Relation as a Tracer of the Merger History of Disk Galaxies
Lekshmi Thulasidharan, Elena D'Onghia, Robert Benjamin +2
In the hierarchical framework of galaxy formation, disk galaxies are shaped by a sequence of mergers and interactions, yet reconstructing this history from observations remains cha…
An Acceleration is Worth a Hundred Thousand Phase Space Measurements
Thomas Donlon, Sukanya Chakrabarti, Elena D'Onghia
It is now possible to directly measure the accelerations that arise from the distribution of (dark) matter in the Milky Way. These acceleration-based measurements of the local dark…
Discovery of a Barred-Spiral Galaxy at = 3.16 II. The Star Formation History
Yingjie Cheng, Mauro Giavalisco, Daniel Ivanov +6
We present a detailed analysis of a massive barred galaxy at using deep multi-band imaging from HST and JWST. For the first time, we resolve its morphology and st…
Discovery of a Barred-Spiral Galaxy at = 3.16 I: Bar Identification and Properties
Daniel Ivanov, Mauro Giavalisco, Yingjie Cheng +6
The formation of stellar bars is an important milestone in the secular evolution of spiral galaxies, which typically indicates the presence of a massive rotationally supported disk…
Exploring the Relationship Between Bars, Star Formation Activity, and Host Galaxy Properties from to
Eden Wise, Shardha Jogee, Yuchen Guo +20
We present the most comprehensive study to date of the relationship between bars, star formation, and galaxy properties from 0 to 2. We use a mass-complete sample…
