Spectroscopic Analysis of Fermi-detected Blazars using SDSS-V
Mohammed Iddrisu Nlowie, James Aird, Eli Kasai +17
The paper introduces a multi-component spectral fitting pipeline applied to SDSS‑V spectra of Fermi‑detected blazars, reclassifying many misidentified sources, improving redshift e…
Detection of Variability in Seyfert 2 Galaxies and Measurement of the Optical Scattering Region Size
Natalie Kovacevic, Xinyu Dai, Heechan Yuk +5
One main theme of the Unification Model of active galactic nuclei is that there is an obscuring torus structure blocking the direct view of the central engine for Seyfert 2 galaxie…
The shortest detected intra-day variability of active galactic nuclei in TESS survey
Heechan Yuk, Xinyu Dai, Natalie Kovacevic
AGNs are known to be variable in almost all wavelengths and timescales. The shortest variability timescale of AGNs can be used to probe the smallest scale structures within AGNs. W…
A Decade-Long Increasing Mid-Infrared Luminosity in Galaxy NGC6447: a Turning-On Candidate of Active Galactic Nucleus
Xinyu Dai, Nate Adams, Natalie Kovacevic +6
It is widely expected that the obscured accretion stage can be the initial turning-on stage of active galactic nuclei from quiescent galaxies. We present mid-infrared light curves…
Formation of Cosmic Noon Protogalaxies via Quasar-Induced Fragmentation of a Cosmic Filament
Marko MiÄiÄ, Themiya Nanayakkara, Xinyu Dai +2
When black hole jets encounter ambient medium, they can compress the gas, trigger star formation, and create stellar clusters containing tens of thousands of stars. Here, we report…
Environmental Dependence of X-Ray Emission From The Least Massive Galaxies
Marko MiÄiÄ, Xinyu Dai, Nick Shumate +2
The low-mass end of low-mass galaxies is largely unexplored in AGN studies, but it is essential for extending our understanding of the black hole-galaxy coevolution. We surveyed th…
