A Nonrepeating Fast Radio Burst in a Dwarf Host Galaxy [PDF]
The Astrophysical Journal, 2023 We present the discovery of an as yet nonrepeating fast radio burst (FRB), FRB 20210117A, with the Australian Square Kilometre Array Pathfinder (ASKAP), as a part of the Commensal Real-time ASKAP Fast Transients Survey.

Dwarf Galaxies in Voids: Dark Matter Halos and Gas Cooling [PDF]
Advances in Astronomy, 2010 Galaxy surveys have shown that luminous galaxies are mainly distributed in large filaments and galaxy clusters. The remaining large volumes are virtually devoid of luminous galaxies.

Contribution of stripped nuclear clusters to globular cluster and ultra-compact dwarf galaxy populations [PDF]
, 2014 We use the Millennium II cosmological simulation combined with the semi-analytic galaxy formation model of Guo et al. (2011) to predict the contribution of galactic nuclei formed by the tidal stripping of nucleated dwarf galaxies to globular cluster (GC)

Dehnen halo effect on a black hole in an ultra-faint dwarf galaxy [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 There had been recent advancement toward the detection of ultra-faint dwarf galaxies, which may serve as a useful laboratory for dark matter exploration since some of them contains almost 99% of pure dark matter. The majority of these galaxies contain no

An extended halo around an ancient dwarf galaxy [PDF]
Nature Astronomy, 2020 The Milky Way is surrounded by dozens of ultrafaint (107 M☉, consistent with a generalized Navarro–Frenk–White density profile. The extended nature of Tucana II suggests that it may have undergone strong bursty feedback or been the product of an early ...

Formation of Transitional cE/UCD Galaxies through Massive/Dwarf Disc Galaxy Mergers
Galaxies, 2023 The dynamics of the merger of a dwarf disc galaxy with a massive spiral galaxy of the Milky Way type were studied in detail. The remnant of such interaction after numerous crossings of the satellite through the disc of the main galaxy was a compact ...

Dependence of stellar substructures in M31 type galaxy on satellite morphology in galaxy mergers [PDF]
Serbian Astronomical Journal, 2022 Stellar streams and shells are observed in halos of spiral galaxies. In this paper, we investigated the formation of these structures due to mergers between the host spiral galaxy and its dwarf satellite galaxies.
