Variable star monitoring in local group dwarf irregular galaxies [PDF]
International Astronomical Union Colloquium, 2004 AbstractDwarf galaxies in the local group provide a unique astrophysical laboratory. Despite their proximity some of these systems still lack reliable distance determinations as well as studies of their stellar content and star formation history. We present first results of our survey of variable stars in a sample of six local group dwarf irregular ...

A Luminous X-Ray Active Galactic Nucleus in the Dwarf–Dwarf Galaxy Merger RGG 66
The Astrophysical JournalWe present the discovery of a luminous X-ray active galactic nucleus (AGN) in the dwarf galaxy merger RGG 66. The black hole is predicted to have a mass of M _BH ∼ 10 ^5.4 M _⊙ and to be radiating close to its Eddington limit ( L _bol / L _Edd ∼ 0.75 ...

The Astrophysical Journal, 2023 Mrk 71 is a low-metallicity ( Z = 0.16 Z _☉ ) starburst region in the local dwarf galaxy NGC 2366, hosting two super star clusters (SSCs A and B), and it is recognized as a Green Pea (GP) analog with SSC A responsible for the GP properties.

Chemical evolution of dwarf irregular and blue compact galaxies [PDF]
Astronomy & Astrophysics, 2011 Dwarf irregular and blue compact galaxies are very interesting objects since they are relatively simple and unevolved. We present new models for the chemical evolution of these galaxies by assuming different regimes of star formation (bursting and continuous) and different kinds of galactic winds (normal and metal-enhanced).

The Astrophysical JournalWe present an imaging survey of the Spitzer I star-forming region in NGC 6822 conducted with the NIRCam and MIRI instruments on board JWST. Located at a distance of 490 kpc, NGC 6822 is the nearest non-interacting low-metallicity (∼0.2 Z _⊙ ) dwarf ...
