Dynamics of Molecular Gas in the Central Region of the Quasar I Zwicky 1

The Astrophysical Journal, 2023
We present a study of the molecular gas distribution and kinematics in the cicumnuclear region (radii ≲2 kpc) of the z ≈ 0.061 quasar I Zwicky 1 using a collection of available Atacama Large Millimeter/submillimeter Array observations of the carbon ...

Gas Dynamics in the Barred Seyfert Galaxy NGC4151 - II. High Resolution HI Study

, 1998
We present sensitive, high angular resolution (6" x 5") 21-cm observations of the neutral hydrogen in the nearby barred Seyfert galaxy, NGC4151. These HI observations, obtained using the VLA in B-configuration, are the highest resolution to date of this ...

An Equilibrium Model of the Galaxy Determined by Element Abundance Gradients

The Astrophysical Journal
We present a method to determine the gravitational potential of the Milky Way from measurements of the locations, velocities, and element abundances of stars in the Galactic disk.

The Jet-Driven Outflow In The Radio Galaxy SDSS J1517+3353: Implications For Double-Peaked Narrow-Line Active Galactic Nucleus [PDF]

, 2010
We report on the study of an intriguing active galaxy that was selected as a potential multiple supermassive black hole merger in the early-type host SDSS J151709.20+335324.7 (z = 0.135) from a complete search for double-peaked [O III] lines from the ...

A Slowly Pulsating Run‐Away B Star at High Galactic Latitude Ejected From a Spiral Arm

Astronomische Nachrichten, Volume 346, Issue 5, June 2025.
ABSTRACT We report the discovery of the young B6 V run‐away star LAMOST J083323.18 + 430825.4, 2.5 kpc above the Galactic plane. Its atmospheric parameters and chemical composition are determined from LAMOST spectra, indicating normal composition. Effective temperature (Teff$$ {T}_{\mathrm{eff}} $$ = 14,500$$ \mathrm{14,500} $$ K) and gravity (logg ...

Galactic outflows and the kinematics of damped Lyman alpha absorbers [PDF]

, 2010
The kinematics of damped Lyman alpha absorbers (DLAs) are difficult to reproduce in hierarchical galaxy formation models, particularly the preponderance of wide systems.

Minor axis kinematics of 19 S0-Sbc bulges

, 2003
We present minor axis kinematic profiles for a well-studied sample of 19 early- to intermediate-type disk galaxies. We introduce, for the first time, the use of single-burst stellar population (SSP) models to obtain stellar velocities, velocity ...

Extented ionized gas emission and kinematics of the compact group galaxies in HCG 16: Signatures of mergers [PDF]

, 1998
We report on kinematic observations of Ha emission line from four late-type galaxies of Hickson Compact Group 16 (H16a,b,c and d) obtained with a scanning Fabry-Perot interferometer and samplings of 16 km/s and 1".

The AURORA Survey: Tracing Galactic Outflows at z ≳ 2.5 with JWST/NIRSpec Near-ultraviolet Absorption Lines

The Astrophysical Journal
We probe galactic-scale outflows in star-forming galaxies at z  ≳ 2.5 drawn from the JWST/NIRSpec AURORA program. For the first time, we directly compare outflow properties from the early Universe to the present day using near-UV absorption lines.
