The rotation curves shapes of late-type dwarf galaxies [PDF]

, 2008
We present rotation curves derived for a sample of 62 late-type dwarf galaxies that have been observed as part of the Westerbork HI Survey of Spiral and Irregular Galaxies (WHISP) project.

MobiCOP: A Scalable and Reliable Mobile Code Offloading Solution

Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018
Code offloading is a popular technique for extending the natural capabilities of mobile devices by migrating processor‐intensive tasks to resource‐rich surrogates. Despite multiple platforms for offloading being available in academia, these frameworks have yet to permeate the industry.

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 ...

The Outer Edges of Dwarf Irregular Galaxies: Stars and Gas

, 2002
We have in recent years come to view dwarf galaxy evolution in the broader context of the cosmic evolution of large-scale structure. Dwarf galaxies, as the putative building blocks of hierarchical galaxy formation, and also as the most numerous galaxies ...

Tidal dwarfs in the M81 group: the second generation? [PDF]

, 2002
We derive quantitative star formation histories of the four suspected tidal dwarf galaxies in the M81 group, HolmbergIX, BK3N, Arp-loop (A0952+69), and Garland, using Hubble Space Telescope/Wide Field Planetary Camera2 images in F606W and F814W obtained ...

A turbulence study in Dwarf Irregular galaxies [PDF]

Proceedings of the International Astronomical Union, 2006
AbstractWe present preliminary results of a Fourier transform power spectra analysis carried out on a sample of dwarf irregular galaxies and Local Group members. This project is intended to study turbulence and the ISM structure in irregulars as a class.

Bose‐Einstein Condensate Dark Matter Halos Confronted with Galactic Rotation Curves

Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017
We present a comparative confrontation of both the Bose‐Einstein Condensate (BEC) and the Navarro‐Frenk‐White (NFW) dark halo models with galactic rotation curves. We employ 6 High Surface Brightness (HSB), 6 Low Surface Brightness (LSB), and 7 dwarf galaxies with rotation curves falling into two classes.

A Young Star Cluster in the Leo a Galaxy

Open Astronomy, 2015
We report a serendipitous discovery of a star cluster in the dwarf irregular galaxy Leo A. Young age (~28 Myr) and low mass (~510 M⊙) estimates are based on the isochrone fit assuming a metallicity derived for HII regions (Z = 0.0007).

Coevolution of Dust and Chemistry in Galaxy Simulations with a Resolved Interstellar Medium

The Astrophysical Journal, 2023
Nearby dwarf irregular galaxies are ideal laboratories for studying the interstellar medium (ISM) at low metallicity, which is expected to be common for galaxies at very high redshift being observed by JWST. We present the first high-resolution (∼0.2 pc)

A Comprehensive Archival Search for Counterparts to Ultra-Compact High Velocity Clouds: Five Local Volume Dwarf Galaxies [PDF]

, 2015
We report five Local Volume dwarf galaxies (two of which are presented here for the first time) uncovered during a comprehensive archival search for optical counterparts to ultra-compact high velocity clouds (UCHVCs).
