When Galaxies Refuel: Evolution of the Perturbed Spiral Galaxy NGC1385
Xiaoyu Kang, Eva Sextl, Rolf-Peter Kudritzki +5
The spiral galaxy NGC 1385 is characterized by a vigorous and protracted history of star formation, particularly in its central regions, leading to a current star formation rate th…
Electromagnetic Flares from Compact-Object Mergers in AGN Disks: Signatures and Predictions
Hiromichi Tagawa, Zoltán Haiman, Shigeo S. Kimura +2
Accretion disks in active galactic nuclei (AGN) are promising sites for mergers of stellar-mass black holes (BHs) detectable via gravitational waves (GWs). These environments facil…
The Narrow-Line Seyfert 1 Phenomenon: Accretion State Versus Host Galaxy Properties
Kaizheng Guo, Hassen M. Yesuf, Lei Hao +3
The physical origin of the narrow-line Seyfert 1 (NLS1) and broad-line Seyfert 1 (BLS1) dichotomy remains debated, with competing scenarios invoking host-galaxy evolution or intrin…
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…
The Importance of Galaxy-Wide Star Formation in Driving Winds at z~1
Weichen Wang, Susan A. Kassin, S. M. Faber +11
In this work, we study winds for a representative sample of 86 star-forming galaxies (SFGs) at z~1 with , by measuring the Mg II line profiles…
Beyond Mass and Multiscale Environments: What Shapes Low Surface Brightness Galaxies? Evidence from MaNGA
Mengting Shen, Hassen M. Yesuf, Lei Hao +4
The origin of low surface brightness (LSB) galaxies remains a key open question in galaxy formation, reflecting the balance internal mechanisms and environmental influence. Using M…
