22 Newly Identified Repeating Changing-look AGNs and Evidence for Extreme Broad-line Region Breathing
Litao Zhu, Zhongxiang Wang, Alok C. Gupta +5
Changing-look active galactic nuclei (CL AGNs) show the appearance or disappearance of broad emission lines on timescales of years. Among them, the repeating CL (RCL) AGNs may prov…
Extreme color-magnitude variability: connection to changing-look AGNs
Litao Zhu, Zhongxiang Wang, Alok C. Gupta +5
Context. Changing-look active galactic nuclei (CL-AGNs) challenge the unified model of AGNs and offer key insights into the physics of the accretion processes of super-massive blac…
Random gas motions inside sub-parsec scale supercritical filaments
Chao Zhang, Tie Liu, Mika Juvela +12
Supercritical gas filaments in molecular clouds host the dense cores in which new stars form. The mechanisms governing their formation and subsequent gas accretion remain poorly un…
HOTDISK. Finding Massive Protostellar Disks with Water and Refractory Molecular Species
Kai Yang, Yichen Zhang, Kei E. I. Tanaka +16
We present high-angular-resolution (, au) ALMA Band~6 observations from the HOTDISK project (Hot-Origin Tracer survey of DISKs of massive pro…
HETDEX Public Data Release 1: Source Catalog 2 and Data Cubes from ~90 sq deg of Integral-Field Optical Spectroscopy
Erin Mentuch Cooper, Karl Gebhardt, Dustin Davis +36
The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) is a wide-field, integral-field spectroscopic survey designed to map the large-scale distribution of Lyman-alpha emitting…
New Dynamical Measurements from a Lensed Quasar Sample: Joint Analysis Constrains the Mass Profile Evolution of Lens Galaxies
Ziyu Guo, Yun Chen, Yiping Shu +4
We present a systematic study of the internal mass structure of early-type galaxies (ETGs) based on 106 galaxy-scale strong gravitational lenses with background quasars, all having…
