Luminous AGB variables in the dwarf irregular galaxy, NGC 3109 [PDF]
Monthly notices of the Royal Astronomical Society, 2018 In a shallow near-infrared survey of the dwarf Irregular galaxy, NGC 3109, near the periphery of the Local Group, we have found eight Mira variables, seven of which appear to be oxygen-rich (O-Miras).

Distance and reddening of the Local Group dwarf irregular galaxy NGC 6822 [PDF]
, 2012 On the basis of a new photometric analysis of the Local Group dwarf irregular galaxy NCG 6822 based on observations obtained with the Advanced Camera for Surveys onboard the Hubble Space Telescope, we have obtained a new estimate of the extinction of two

The faint outer regions of the Pegasus dwarf irregular galaxy: a much larger and undisturbed galaxy [PDF]
, 2009 We investigate the spatial extent and structure of the Pegasus dwarf irregular galaxy (PegDIG) using deep, wide-field, multicolour CCD photometry from the Sloan Digital Sky Survey (SDSS) and new deep H I observations.

Search for dark matter annihilation in the Wolf-Lundmark-Melotte dwarf irregular galaxy with H.E.S.S. [PDF]
Physical Review D, 2021 We search for an indirect signal of dark matter through very high-energy gamma rays from the Wolf-Lundmark-Melotte (WLM) dwarf irregular galaxy. The pair annihilation of dark matter particles would produce Standard Model particles in the final state such

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 ...

Supernova Remnants in the Irregular Galaxy NGC 4449
The Astrophysical Journal, 2023 The nearby irregular galaxy NGC 4449 has a star formation rate of ∼0.4 M _☉ yr ^−1 and should host of order 70 supernova remnants (SNRs) younger than 20,000 yr, a typical age for SNRs expanding into an interstellar medium (ISM) with a density of 1 cm ^−3
