GALACTIC WINDS IN IRREGULAR STARBURST GALAXIES [PDF]

open access: yes, 2001
In this paper we present some results concerning the study of the development of galactic winds in blue compact galaxies. In particular, we model a situation very similar to that of the galaxy IZw18, the most metal poor and unevolved galaxy known locally.

Galaxy Morphological Classification of the Legacy Surveys with Deformable Convolutional Neural Networks

open access: yesThe Astronomical Journal, 2023
The ongoing and forthcoming surveys will result in an unprecedented increase in the number of observed galaxies. As a result, data-driven techniques are now the primary methods for analyzing and interpreting this vast amount of information.

The CO contents of dwarf irregular galaxies

open access: yesThe Astrophysical Journal, 1987
A search has been conducted for CO in 16 dwarf irregular galaxies selected to span a wide range of infrared luminosity and color. CO was detected in six dwarf galaxies spanning the entire range in optical color and IR luminosity. The dwarf galaxies extend by three orders of magnitude in luminosity the correlation between IR and CO luminosities found ...

The Classification of Galaxy Morphology in the H Band of the COSMOS-DASH Field: A Combination-based Machine-learning Clustering Model

open access: yesThe Astrophysical Journal Supplement Series, 2023
By applying our previously developed two-step scheme for galaxy morphology classification, we present a catalog of galaxy morphology for H -band-selected massive galaxies in the COSMOS-DASH field, which includes 17,292 galaxies with stellar mass M _ ...

The Star Formation Across Cosmic Time (SFACT) Survey. III. Spectroscopy of the Initial Catalog of Emission-line Objects

open access: yesThe Astronomical Journal, 2023
The Star Formation Across Cosmic Time (SFACT) survey is a new narrowband survey designed to detect emission-line galaxies (ELGs) and quasi-stellar objects (QSOs) over a wide range of redshifts in discrete redshift windows.

Near-capacity irregular variable length coding and irregular unity rate coding [PDF]

open access: yes, 2009
In this contribution we introduce an EXtrinsic Information Transfer (EXIT) chart matching technique for the design of two serially concatenated irregular codecs, each constituted by a variety of component codes.
