From Clusters to Proto-Clusters: The Infrared Perspective on Environmental Galaxy Evolution

open access: yesUniverse, 2022
Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it can control the critical process of transforming galaxies from star forming to quiescent, commonly termed “quenching”. Despite its importance, however, we still do

A Near-infrared-faint, Far-infrared-luminous Dusty Galaxy at z ∼ 5 in COSMOS-Web

open access: yesThe Astrophysical Journal, 2023
A growing number of far-infrared (FIR) bright sources completely invisible in deep extragalactic optical surveys hint at an elusive population of z > 4 dusty, star-forming galaxies.

Mid-infrared Outbursts in Nearby Galaxies: Nuclear Obscuration and Connections to Hidden Tidal Disruption Events and Changing-look Active Galactic Nuclei

open access: yesThe Astrophysical Journal Letters, 2023
We study the properties of galaxies hosting mid-infrared outbursts in the context of a catalog of 500,000 galaxies from the Sloan Digital Sky Survey. We find that nuclear obscuration, as inferred by the surrounding dust mass, does not correlate with host

Rest-frame Near-infrared Radial Light Profiles up to z = 3 from JWST/NIRCam: Wavelength Dependence of the Sérsic Index

open access: yesThe Astrophysical Journal, 2023
We examine the wavelength dependence of radial light profiles based on Sérsic index n measurements of 1067 galaxies with M _* ≥ 10 ^9.5 M _⊙ and in the redshift range 0.5 < z < 3. The sample and rest-frame optical light profiles are drawn from the Cosmic

What is driving the evolution of the far-infrared radio correlation? [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2019
Far infrared-radio correlation represents a linear relationship between far-infrared (FIR) and radio emission in star-forming galaxies. Previous observations have confirmed that this correlation is maintained over a large range of redshift and ...

The Role of Radio Observations in Studies of Infrared-Bright Galaxies: Prospects for a Next-Generation Very Large Array

open access: yesUniverse, 2022
The bulk of the present-day stellar mass was formed in galaxies when the universe was less than half its current age (i.e., 1≲z≲3). While this likely marks one of the most critical time periods for galaxy evolution, we currently do not have a clear ...

A New Wide-field Infrared Survey Explorer Calibration of Stellar Mass

open access: yesThe Astrophysical Journal, 2023
We derive new empirical scaling relations between Wide-field Infrared Survey Explorer (WISE) mid-IR (MIR) galaxy photometry and well-determined stellar masses from spectral energy distribution modeling of a suite of optical–infrared photometry provided ...

Simulations of High-redshift [O iii] Emitters: Chemical Evolution and Multiline Diagnostics

open access: yesThe Astrophysical Journal, 2023
Recent observations by the James Webb Space Telescope discovered a number of high-redshift galaxies with strong emission lines from doubly ionized oxygen.

Dust and gas in star-forming complexes in NGC 3351, NGC 5055, and NGC 5457

open access: yesOpen Astronomy, 2023
We present a study of the interstellar medium parameters in star-forming complexes (SFCs) in NGC 3351, NGC 5055, and NGC 5457 galaxies. This study concludes our previous investigations of gas and dust in a number of spiral galaxies.

GOALS-JWST: Mid-infrared Spectroscopy of the Nucleus of NGC 7469

open access: yesThe Astrophysical Journal Letters, 2023
We present mid-infrared spectroscopic observations of the nucleus of the nearby Seyfert galaxy NGC 7469 taken with the MIRI instrument on the James Webb Space Telescope (JWST) as part of Directors Discretionary Time Early Release Science program 1328 ...
