Integral Field Spectroscopy of Seyfert Galaxies [PDF]

Publications of the Astronomical Society of the Pacific, 2001
The present work is based on a spectroscopically selected sample of Seyfert galaxies and consists of the observation, reduction, and analysis of three-dimensional data, obtained through the MPFS, the integral field spectrograph designed and developed by the scientists of the Special Astrophysical Observatory (Russia) for the 6 m telescope.

The ∞ Galaxy: A Candidate Direct-collapse Supermassive Black Hole between Two Massive, Ringed Nuclei

The Astrophysical Journal Letters
We report the discovery of an unusual z = 1.14 object, dubbed the ∞ galaxy, in JWST imaging of the COSMOS field. Its rest-frame near-IR light is dominated by two compact nuclei with stellar masses of ∼10 ^11 M _⊙ and a projected separation of 10 kpc ...

The Star-forming Main Sequence in JADES and CEERS at z > 1.4: Investigating the Burstiness of Star Formation

The Astrophysical Journal
We have used public JWST/NIRSpec and JWST/NIRCam observations from the CEERS and JADES surveys in order to analyze the star-forming main sequence (SFMS) over the redshift range 1.4 ≤ z < 7.

CANUCS/Technicolor Data Release 1: Imaging, Photometry, Slit Spectroscopy, and Stellar Population Parameters

The Astrophysical Journal Supplement Series
We present the first data release of the Canadian NIRISS Unbiased Cluster Survey (CANUCS), a JWST Cycle 1 GTO program targeting five lensing clusters and flanking fields in parallel (A370, MACS0416, MACS0417, MACS1149, and MACS1423; survey area ∼100 ...

A Simulated Galaxy Laboratory: Exploring the Observational Effects on UV Spectral Absorption Line Measurements

The Astrophysical Journal
Ultraviolet absorption line spectroscopy is a sensitive diagnostic for the properties of interstellar and circumgalactic gas. Down-the-barrel observations, where the absorption is measured against the galaxy itself, are commonly used to study feedback ...

HST Grism Observations of a z ∼ 1.8 Cluster Candidate from the Clusters Occupied by Bent Radio AGN (COBRA) Survey

The Astrophysical Journal
We present new Hubble Space Telescope/Wide Field Camera 3 G141 grism observations for COBRA 1411+3415, originally identified as a high-redshift cluster candidate in the Clusters Occupied by Bent Radio AGN (COBRA) survey using radio, infrared, and optical
