Constraints on the presence of water megamaser emission in z~2.5 ultraluminous infrared starburst galaxies

, 2009
We present Expanded Very Large Array and Arecibo observations of two lensed submm galaxies at z~2.5, in order to search for redshifted 22.235 GHz water megamaser emission.

No Metallicity Preference in Fast Radio Burst Host Galaxies

The Astrophysical Journal Letters
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio transients of unknown origin, and studying their host galaxies could offer clues to constrain progenitor models.

The Starburst – AGN Connection: a Critical Review

Open Astronomy, 2011
Nuclear activity and star formation processes represent two key elements in the evolution of galaxies across the cosmic ages. In spite of very different physical backgrounds, several arguments suggest that they should be closely connected.

How Accurately Can Obscured Galaxy Luminosities Be Measured Using Spectral Energy Distribution Fitting of Near- through Far-infrared Observations?

The Astrophysical Journal
Infrared-luminous galaxies are important sites of stellar and black hole mass assembly at most redshifts. Their luminosities are often estimated by fitting spectral energy distribution (SED) models to near- to far-infrared data, but the dependence of ...

Starbursts and Galaxy Evolution

, 2004
Starbursts are extreme concentrations of star-forming activity with mass conversion surface densities reaching over 1000 times higher than normal for disk galaxies. They are responsible for a large fraction of all cosmic star formation. They have shaped the cosmic landscape not just in individual galaxies but though the effects of "superwinds" that ...

Machine Learning Classification of COSMOS2020 Galaxies: Quiescent versus Star-forming

The Astrophysical Journal
Accurately distinguishing between quiescent and star-forming galaxies is essential for understanding galaxy evolution. Traditional methods, such as spectral energy distribution (SED) fitting, can be computationally expensive and may struggle to capture ...
