Star Formation at the Epoch of Reionization with CANUCS: The Ages of Stellar Populations in MACS1149-JD1

The Astrophysical Journal Letters
We present measurements of stellar populations properties of a z = 9.1 gravitationally lensed galaxy MACS1149-JD1 using deep James Webb Space Telescope NIRISS slitless spectroscopy as well as NIRISS and NIRCam imaging from the CAnadian NIRISS Unbiased ...

ISO spectroscopy of luminous galaxies

, 2016
Spectroscopy with SWS and ISOPHOT-S has opened a new window for studies of the nuclei of external galaxies. We present selected results of observations of starburst galaxies and active galactic nuclei and discuss the mid-infrared extinction law. The flux ratio of high and low excitation fine structure lines and the strength of the 'PAH' emission ...

A Massive Quiescent Galaxy in a Group Environment at z = 4.53

The Astrophysical Journal
We report on the spectroscopic confirmation of a massive quiescent galaxy at z _spec = 4.53 in the COSMOS field. The object was first identified as a galaxy with suppressed star formation at z _phot ∼ 4.65 from the COSMOS2020 catalog.

Morphology and Kinematics of the Gas in M51: How Interaction with NGC 5195 Has Molded the Structure of Its Arms

The Astrophysical Journal
The Whirlpool Galaxy is a well-studied grand design galaxy with two major spiral arms, and a large satellite NGC 5195. The arms both show long uniform sections with perturbations (“kinks” or sharp turns) in specific regions.

RUBIES Reveals a Massive Quiescent Galaxy at z = 7.3

The Astrophysical Journal
We report the spectroscopic discovery of a massive quiescent galaxy at z _spec  = 7.29 ± 0.01, just  ∼700 Myr after the big bang. RUBIES-UDS-QG-z7 was selected from public JWST/NIRCam and MIRI imaging from the PRIMER survey and observed with JWST/NIRSpec

Blowing Star Formation Away in Active Galactic Nuclei Hosts. I. Observation of Warm Molecular Outflows with JWST MIRI

The Astrophysical Journal
We use the James Webb Space Telescope Mid-Infrared Instrument medium-resolution spectrometer observations of the radio-loud active galactic nucleus (AGN) host UGC 8782 to map the warm molecular and ionized gas kinematics.
