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

A complete redshift sample of galaxies [PDF]

, 1983
The role of complete redshift samples is discussed with particular attention focused on the need for new deeper and better controlled surveys for statistical clustering and dynamical studies.

Galaxy morphology classification: are stellar circularities enough? [PDF]

Serbian Astronomical Journal
We present a preliminary study exploring whether the stellar orbital circularity of simulated galaxies, available from precomputed catalogs in the IllustrisTNG project, can be used as a proxy for a broad morphological classification. We focus on

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 ...

Near-capacity irregular variable length coding and irregular unity rate coding [PDF]

, 2009
In this contribution we introduce an EXtrinsic Information Transfer (EXIT) chart matching technique for the design of two serially concatenated irregular codecs, each constituted by a variety of component codes.

Star clusters in unperturbed spiral galaxies [PDF]

, 2008
Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.

Morphology Classification for Galaxies in the Kilo Degree Survey Using a Label-efficient Self-supervised Learning Framework

The Astrophysical Journal Supplement Series
Galaxy morphology classification is fundamental to understanding galaxy formation and evolution. The advent of large-scale sky surveys has produced an unprecedented volume of galaxy images, making traditional manual classification impractical.
