Handy Relation between Binary Black Hole Merger Times and Host Galaxy Properties

The Astrophysical Journal Letters
Over the past 15 yr, the evidence has clearly demonstrated that massive black hole (MBH) binary merger timescales depend strongly on the structural and kinematic properties of their host galaxy.

The Sunburst Arc with JWST. IV. The Importance of Interaction, Turbulence, and Feedback for Lyman-continuum Escape

The Astrophysical Journal
At present, the best opportunity for detailed Lyman continuum (LyC) escape studies is in gravitationally lensed galaxies at z  ≳ 2. Only one such galaxy currently exists in the literature with sufficient magnification and spatial resolution: the Sunburst

Caught in the act: Interaction-driven evolution in the nearby compact galaxy group Robert’s Quartet (SCG0018-4854)

Astronomy & Astrophysics
We present a spatially resolved multiwavelength study of the compact galaxy group Robert’s Quartet (RQ; SCG0018-4854), aimed at understanding interaction-driven galaxy evolution in dense environments.

Kinematic and Dynamics of the Galaxy ESO 358-60

The Astrophysical Journal
We investigate the velocity field derived from H I measurements of the irregular galaxy ESO 358-60 using the velocity ring model (VRM) method. This technique, which assumes a coplanar disk, allows us to reconstruct coarse-grained maps of both radial and ...

Visit Nearby Halo Substructures Using LAMOST DR9 MRS Data

The Astrophysical Journal
Based on the LAMOST DR9 Medium Resolution Spectra (MRS) catalog, combined with astrometries from Gaia DR3, we conducted an investigation into the substructures in the stellar halo to obtain their chemical and kinematic information.

High-resolution Optical IFU Spectroscopy of the Complex Galaxy Merger II Zw 096

The Astrophysical Journal
Luminous and ultraluminous IR galaxies are critical for investigating feedback mechanisms due to a combination of intense star formation episodes and active galactic nuclei (AGN), particularly in the context of complex galaxy interactions.

Physical characterization of the local system NGC 1313: A flattening in its chemical abundance by past interactions

Astronomy & Astrophysics
Context. Interacting galaxies provide unique information on morphological transformation, enhanced star formation, and chemical evolution, and thus contribute to understanding the complex evolution of galaxies. Aims. We investigated the local interacting

A Stellar Dynamical Mass for the Central Black Hole in MCG–06-30-15

The Astrophysical Journal
We present the stellar dynamical (SD) mass of the central black hole in the nearby Seyfert galaxy MCG–06-30-15 using the Schwarzschild orbit-superposition method implemented in the open-source code FORSTAND .
