Wave Cold Dark Matter Can Reproduce the Radial Acceleration Relation in X-ray Elliptical Galaxies
Runyu Meng, Xiaobo Dong
Wave cold dark matter (wave CDM) is a well-motivated variant within the collisionless CDM paradigm, in which the de~Broglie wavelengths of ultralight bosons become relevant on gala…
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…

Deblending the MIGHTEE-COSMOS survey with XID+: The resolved radio source counts to Jy
Eliab D. Malefahlo, Matt J. Jarvis, Mario G. Santos +9
Deep radio continuum surveys provide fundamental constraints on galaxy evolution, but source confusion limits sensitivity to the faintest sources. We present a complete framework f…
The Nearby Evolved Stars Survey III: First data release of JCMT CO-line observations
S. H. J. Wallström, P. Scicluna, S. Srinivasan +37
Low- to intermediate-mass (0.88 M) evolved stars contribute significantly to the chemical enrichment of the interstellar medium in the local Universe, making accur…
Unveiling the nature and fate of the almost-dark cloud AGC 226178 through HI mapping
Yu-Zhu Sun, Hong-Xin Zhang, Elias Brinks +18
The origin of extragalactic, almost dark HI clouds with extreme gas-to-stellar mass ratios remains poorly understood. We investigate the nature and fate of the "almost dark" cloud…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XIV. Long-Duration High-Cadence Reverberation Mapping Results for 11 PG Quasars

We report the results of a long-duration high-cadence reverberation mapping campaign of a second batch of 11 PG quasars using the 2.2m telescope at the Calar Alto Observatory. This…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XII. Reverberation Mapping Results for 15 PG Quasars from a Long-Duration High-Cadence Campaign
Chen Hu, Sha-Sha Li, Sen Yang +15
We present the first results from long-term high-cadence spectroscopic monitoring of 15 PG quasars with relatively strong Fe II emission as a part of a broader reverberation mappin…
A Morphological Study on AGN-host Dwarf Galaxies
Jie Tian, Yinghe Zhao, Xiejin Li +1
The study of morphology in galaxies offers a convenient and quantitative method to measure the shapes and characteristics of galaxy light distribution that reflect the evolutionary…
Metallicity dependence of the CO-to-H and the [CI]-to-H conversion factors in galaxies
Thomas G. Bisbas, Zhi-Yu Zhang, Maria-Christina Kyrmanidou +6
Understanding the molecular gas content in the interstellar medium (ISM) is crucial for studying star formation and galaxy evolution. The CO-to-H () and the [CI]-to…
Optical+NIR analysis of a Newly Confirmed Einstein ring at z1 from the Kilo-Degree Survey: Dark matter fraction, total and dark matter density slope and IMF
Rui Li, Nicola R. Napolitano, Giuseppe D Ago +16
We report the spectroscopic confirmation of a bright blue Einstein ring in the Kilo Degree Survey (KiDS) footprint: the Einstein ``blue eye''. Spectroscopic data from X-Shooter at…
Two categories of UV-upturn galaxies revealed by semi-analytic models
Zhen Jiang, Cheng Li, Fenghui Zhang +1
UV-upturn galaxies are characterized by unusually excessive flux in the far-ultraviolet (FUV) band, observed in some elliptical galaxies and the bulges of disk galaxies. We examine…
Testing Colour-magnitude Pattern as A Method in the Search for Changing-Look AGNs
Li-tao Zhu, Zhongxiang Wang, P. U. Devanand +6
We develop a simple method to search for changing-look (CL) active galactic nucleus (AGN) candidates, and conduct a test run. In this method, optical variations of AGNs are monitor…
