WLM: Dynamics of an isolated dwarf irregular galaxy under ram pressure in the Local Group
Astronomy & AstrophysicsThe Wolf–Lundmark–Melotte (WLM) galaxy is an archetypal dwarf irregular galaxy that has not experienced interactions with major Local Group galaxies within the past 8 Gyr.

ON THE STAR FORMATION LAW FOR SPIRAL AND IRREGULAR GALAXIES [PDF]
The Astrophysical Journal, 2015 A dynamical model for star formation on a galactic scale is proposed in which the interstellar medium is constantly condensing to star-forming clouds on the dynamical time of the average midplane density, and the clouds are constantly being disrupted on the dynamical time scale appropriate for their higher density.

FIGGS Faint Irregular Galaxies GMRT Survey [PDF]
, 2008 The Faint Irregular Galaxies GMRT Survey (FIGGS) is a large program aimed at providing a comprehensive and statistically robust characterisation of the neutral ISM properties of faint (M_B > -14.5), nearby, gas rich, dwarf irregular galaxies using the Giant Metrewave Radio Telescope (GMRT). Here we briefly describe the survey and discuss some of the

Ultradeep Imaging of Nearby Dwarf Irregular Galaxies: Young Objects in the Far Outer Disk
The Astronomical JournalUltradeep UBVI imaging of 10 nearby (≤7.8 Mpc) noninteracting dwarf irregular galaxies are used to examine their far outer stellar disks. The annulus between 26 mag arcsec ^−2 and 29 mag arcsec ^−2 in the V band is what we define as the far outer disk ...

Dissecting the Perseus-Pisces supercluster observed with CFHT-MegaCam
Astronomy & AstrophysicsThe discovery of the large-scale structure of the Universe has fundamentally reshaped our understanding of galaxy formation and evolution. Filaments of the cosmic web act as privileged environments, guiding the growth of structures.

PIDE-Working Papers: no. 2021:4. COVID-19, irregular migration and asymmetrical dependency [PDF]
, 2021 "This study explores the process of irregular migration that drives people to opt for illegal channels to migrate. The study further examines the impact of the COVID-19 pandemic on the socio-economic vulnerabilities of irregular migrant workers.

Fragmentation of Expanding Shells in Spiral and Irregular Galaxies
Astronomy & Astrophysics, 1997 Conditions for the fragmentation of expanding shells due to gravitational instability are discussed. The self-similar analytical solution is compared with the results of 3-dimensional computer simulations for the expansion into homogeneous media. For realistic galactic disks we show that the formation of fragments is influenced by the amount of energy ...
