Dwarf Spheroidal Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1994
Dwarf Spheroidal (dSph) galaxies are the faintest baryonic systems recognized as galaxies. Understanding the structure and stellar populations of these systems is critical for the modelling of their formation and evolution, and by extension, for understanding the general problem of galaxy formation ...

Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program

open access: yesThe Astrophysical Journal, 2023
We introduce the DESI LOW- Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method.

Dwarf Galaxies in the Local Volume [PDF]

open access: yesAstrophysical Bulletin, 2018
AbstractThe Updated Nearby Galaxy Catalog (=UNGC) of 1047 Local Volume (=LV) galaxies, situated within a distance of 11 Mpc, contains 870 dwarfs, i.e. 5/6 of the sample. Almost 40% of them have accurate distances measured with Hubble Space Telescope. Most of the LV dwarfs have been observed in HI and Hα emission lines, as well in far-ultraviolet with ...

A Comparison of Outflow Properties in AGN Dwarfs versus Star-forming Dwarfs

open access: yesThe Astrophysical Journal, 2023
Feedback likely plays a crucial role in resolving discrepancies between observations and theoretical predictions of dwarf galaxy properties. Stellar feedback was once believed to be sufficient to explain these discrepancies, but it has thus far failed to

Metallic Winds in Dwarf Galaxies [PDF]

open access: yesThe Astrophysical Journal, 2017
Abstract We present results from models of galactic winds driven by energy injected from nuclear (at the galactic center) and non-nuclear starbursts. The total energy of the starburst is provided by very massive young stellar clusters, which can push the galactic interstellar medium and produce an important outflow. Such outflow can be a

A Stellar Mass Threshold for Quenching of Field Galaxies

open access: yes, 2012
We demonstrate that dwarf galaxies (10^7 < M_stellar < 10^9 Msun) with no active star formation are extremely rare (
