Super-Eddington Accretion and Early-Stage Feedback in Ton S180
Pierpaolo Condò, Giacomo Venturi, Eleonora Parlanti +15
Narrow-line Seyfert 1 (NLSy1) galaxies are key laboratories for studying rapid supermassive black hole (SMBH) growth and active galactic nucleus (AGN) feedback at high accretion ra…
Constraints on the Intranight Optical Variability of Intermediate-Mass Black Hole Candidates
Wenwen Zuo, Hengxiao Guo, Wanling Liu +12
Intermediate-mass black holes (IMBHs) provide a unique regime for studying accretion variability at the low-mass end of the black hole population, yet their intranight optical vari…
DESI as sparse Integral Field Spectrograph I: Spatially resolved chemical enrichment in star-forming galaxies at
Vibhore Negi, Ravi Joshi, B. Vishnupriya +8
We present a spatially resolved chemical abundance analysis of 2291 star-forming galaxies at , spanning nearly four orders of magnitude in stellar mass ($8 \le \rm log…
Unraveling the mysteries of Jets in peculiar NLSy1 galaxies through multi-wavelength variability
Vineet Ojha, Xue-Bing Wu, Luis C. Ho +4
Radio-quiet narrow-line Seyfert 1 galaxies (RQ-NLSy1s) are generally considered to be dominated by thermal emission from the accretion disk. However, recurring 37 GHz radio flares…
The Relative Contributions of Accretion Disk versus Jet to the Optical and Mid-infrared Variability of Seyfert Galaxies
Vineet Ojha, Xue-Bing Wu, Luis C. Ho
We performed a comprehensive analysis of flux and color variability in a redshift-matched sample of Seyfert galaxies, comprising 23 gamma-ray-detected narrow-line Seyfert 1 galaxie…
