Chemical behavior of the dwarf irregular galaxy NGC6822. Its PN and HII region abundances [PDF]
, 2009 Aims. We aim to derive the chemical behavior of a significant sample of PNe and HII regions in the irregular galaxy NGC 6822. The selected objects are distributed in different zones of the galaxy.

Spectral Energy Distributions for 258 Local Volume Galaxies
The Astronomical Journal, 2023 We present model spectral energy distribution (SED) fits to ultraviolet/optical/infrared observations for the 258 nearby galaxies in the Local Volume Legacy survey, a sample dominated by lower-luminosity dwarf irregular systems.

Stellar population of the irregular galaxy IC 10 [PDF]
, 2009 Based on our observations with the 6-m BTA telescope at the Special Astrophysical Observatory, the Russian Academy of Sciences, and archival Hubble Space Telescope images, we have performed stellar photometry for several regions of the irregular galaxy ...

A Survey of Galaxy Pairs in the SDSS Photometric Images based on Faster-RCNN
The Astronomical JournalGalaxy pairs hold significant importance in understanding the evolution of galaxies, and the extensive search for a large sample of galaxy pairs is meaningful.

The Astrophysical JournalMeasuring the relation between star formation and galactic winds is observationally difficult. In this work we make an indirect measurement of the mass-loading factor (the ratio between the mass outflow rate and star formation rate) in low-mass galaxies ...

Formation of dwarf ellipticals and dwarf irregular galaxies by interaction of giant galaxies under environmental influence [PDF]
, 2014 A model is proposed for the formation of gas-rich dwarf irregular galaxies and gas-poor, rotating dwarf elliptical galaxies following the interaction between two giant galaxies as a function of space density. The formation of dwarf galaxies is considered to depend on a random variable, the tidal index theta, an environmental parameter defined by ...

The Physical Nature of Rest-UV Galaxy Morphology During the Peak Epoch of Galaxy Formation [PDF]
, 2006 Motivated by the irregular and little-understood morphologies of z ~ 2 - 3 galaxies, we use non-parametric coefficents to quantify the morphologies of 216 galaxies which have been spectroscopically confirmed to lie at redshifts z = 1.8 - 3.4 in the GOODS-

Stellar Populations of Dwarf Irregular Galaxies [PDF]
Symposium - International Astronomical Union, 1996 We recently completed two-color CCD photometry of resolved stars in 11 dwarf irregular galaxies (Hopp & Schulte-Ladbeck, 1995, A&AS 111, 527), selected because of their relative isolation from massive galaxies in the Kran-Korteweg – Tammann sample (1979, AN 300, 181).

‘The non‐dormant beast’: Antisemitism in communities of Russian nationalists on Vkontakte
Nations and Nationalism, EarlyView.Abstract The article explores the specifics of Russian antisemitic discourse of recent years using the example of three nationalist communities on Vkontakte, the most popular Russian social networking site, by means of critical discourse analysis. The main strategies they employ to frame the Jews online are stereotyping Jews as ungrateful and greedy ...
