Theoretical predictions for dark matter detection in dwarf irregular galaxies with gamma rays [PDF]
Physical Review D, 2017 We investigate dwarf irregular(dIrr) galaxies as a new category of targets for indirect Dark Matter(DM) searches with gamma-rays. In the framework of point-like analysis, dwarf spheroidal(dSph) galaxies are usually considered as one of the best category ...

Delayed Massive-star Mechanical Feedback at Low Metallicity
The Astrophysical Journal, 2023 The classical model of massive-star mechanical feedback is based on effects at solar metallicity ( Z _⊙ ), yet feedback parameters are very different at low metallicity.

The Stellar Content of 10 Dwarf Irregular Galaxies [PDF]
The Astronomical Journal, 1998 We examine the stellar content of 10 dwarf irregular galaxies of which broad-band CCD photometry was published in Hopp & Schulte-Ladbeck (1995). We also present Halpha images for several of these galaxies. The galaxies in the sample are located outside of the Local Group.

The Resilience of Habitable Climates Around Circumbinary Stars
Journal of Geophysical Research: Planets, Volume 125, Issue 9, September 2020., 2020 Abstract Here we use a 3‐D climate system model to study the habitability of Earth‐like planets orbiting in circumbinary systems. In the most extreme cases, Earth‐like planets in circumbinary systems could experience variations in the incident stellar flux of up to ~50% on ~100‐day timescales.

LITTLE THINGS in 3D: robust determination of the circular velocity of dwarf irregular galaxies [PDF]
, 2016 Dwarf irregular galaxies (dIrrs) are the smallest stellar systems with extended H I discs. The study of the kinematics of such discs is a powerful tool to estimate the total matter distribution at these very small scales.

A Study of Two Dwarf Irregular Galaxies with AsymmetricalStar Formation Distributions [PDF]
, 2018 Two dwarf irregular galaxies, DDO 187 and NGC 3738, exhibit a striking pattern of star formation: intense star formation is taking place in a large region occupying roughly half of the inner part of the optical galaxy. We use data on the H i distribution

Near-infrared Stellar Populations in the Metal-poor, Dwarf Irregular Galaxies Sextans A and Leo A [PDF]
Proceedings of the International Astronomical Union, 2017 We present JHKs observations of the metal-poor ([Fe/H] < −1.40) dwarf-irregular galaxies, Leo A and Sextans A, obtained with the WIYN High-resolution Infrared Camera at Kitt Peak. Their near-IR stellar populations are characterized by using a combination

Shaken, but not expelled: Gentle baryonic feedback from nearby starburst dwarf galaxies [PDF]
Astronomy & Astrophysics, 2022 Baryonic feedback is expected to play a key role in regulating the star formation of low-mass galaxies by producing galaxy-scale winds associated with mass-loading factors $\beta\!\sim\!1\!-\!50$.

Catching Tidal Dwarf Galaxies at a Later Evolutionary Stage with ALFALFA
The Astronomical Journal, 2023 We present deep optical imaging and photometry of four objects classified as “Almost-Dark” galaxies in the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey because of their gas-rich nature and extremely faint or missing optical emission in ...
