The fundamental properties of galaxies and a new galaxy classification system [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 We present in this paper a new three-dimensional galaxy classification system designed to account for the diversity of galaxy properties in the nearby universe. To construct this system we statistically analyse a sample of >22,000 galaxies at v<15,000 km/s (z<0.05) with Spearman rank and principal component analyses.

Chronicling the Host Galaxy Properties of the Remarkable Repeating FRB 20201124A [PDF]
Astrophysical Journal Letters, 2021 We present the Australian Square Kilometre Array Pathfinder localization and follow-up observations of the host galaxy of the repeating fast radio burst (FRB) source, FRB 20201124A, the fifth such extragalactic repeating FRB with an identified host. From

Mangrove: Learning Galaxy Properties from Merger Trees [PDF]
Astrophysical Journal, 2022 Efficiently mapping baryonic properties onto dark matter is a major challenge in astrophysics. Although semianalytic models (SAMs) and hydrodynamical simulations have made impressive advances in reproducing galaxy observables across cosmologically ...

The connection between the escape of ionizing radiation and galaxy properties at z ∼ 3 in the Keck Lyman continuum spectroscopic survey [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The connection between the escape fraction of ionizing radiation (fesc) and the properties of galaxies, such as stellar mass ($\rm M_{\rm *}$), age, star-formation rate (SFR), and dust content, are key inputs for reionization models, but many of these ...

The PAU survey: measurement of narrow-band galaxy properties with approximate bayesian computation [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Narrow-band imaging surveys allow the study of the spectral characteristics of galaxies without the need of performing their spectroscopic follow-up. In this work, we forward-model the Physics of the Accelerating Universe Survey (PAUS) narrow-band data ...

CEERS Spectroscopic Confirmation of NIRCam-selected z ≳ 8 Galaxy Candidates with JWST/NIRSpec: Initial Characterization of Their Properties [PDF]
Astrophysical Journal Letters, 2023 We present JWST NIRSpec spectroscopy for 11 galaxy candidates with photometric redshifts of z ≃ 9 − 13 and M UV ∈ [ −21, −18] newly identified in NIRCam images in the Cosmic Evolution Early Release Science Survey. We confirm emission line redshifts for 7

Host Galaxy Properties and Offset Distributions of Fast Radio Bursts: Implications for Their Progenitors [PDF]
Astrophysical Journal, 2020 We present observations and detailed characterizations of five new host galaxies of fast radio bursts (FRBs) discovered with the Australian Square Kilometre Array Pathfinder (ASKAP) and localized to ≲1″.

A Comparative Study of Host Galaxy Properties between Fast Radio Bursts and Stellar Transients [PDF]
Astrophysical Journal, 2020 Recent arcsecond localizations of fast radio bursts and identifications of their host galaxies confirmed their extragalactic origin. While FRB 121102 resides in the bright region of a dwarf star-forming galaxy, other FRBs reside in more massive galaxies ...
