The extended structure of the dwarf irregular galaxy Sagittarius [PDF]
, 2014 We present a detailed study of the stellar and HI structure of the dwarf irregular galaxy Sagittarius. We use new deep and wide field photometry to trace the surface brightness profile of the galaxy out to ~5.0' (corresponding to ~1600 pc) and down to ...

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).

The star formation history of the Sculptor Dwarf Irregular Galaxy [PDF]
, 2012 [abridged] We study the resolved stellar populations and derive the SFH of the SDIG, a gas-rich dwarf galaxy member of the NGC7793 subgroup in the Sculptor group. We construct a CMD using archival HST observations and examine its stellar content.

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.

A Wide Field Planetary Camera 2 Study of the Resolved Stellar Population of the Pegasus Dwarf Irregular Galaxy (DDO 216) [PDF]
, 1998 The stellar population of the Pegasus dwarf irregular galaxy is investigated in images taken in the F439W (B), F555W (V), and F814W (I) bands with the Wide Field Planetary Camera 2 (WFPC2) on the Hubble Space Telescope.

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
