Stellar populations in the dwarf irregular galaxy Leo A

open access: yes, 2021
Nykštukinės galaktikos yra dominuojantis galaktikų tipas Visatoje, todėl jos ypač svarbios galaktikų formavimosi ir evoliucijos tyrimų kontekste. Disertacijoje atliktas žvaigždžių populiacijų tyrimas netaisyklingoje nykštukinėje galaktikoje Leo A. Tiriant senas žvaigždžių populiacijas buvo atrastos šviesios asimptotinės milžinių sekos žvaigždės bei ...

The JWST Resolved Stellar Populations Early Release Science Program. VIII. The Spatially Resolved Star Formation History of WLM

open access: yesThe Astrophysical Journal
Radial stellar population gradients within dwarf galaxies provide a promising avenue for disentangling the drivers of galaxy evolution, including environment. Within the Local Volume, radial stellar age gradient slopes correlate with interaction history,

Euclid: Early Release Observations – The star cluster systems of the Local Group dwarf galaxies IC 10 and NGC 6822★

open access: yesAstronomy & Astrophysics
Star clusters are valuable indicators of galaxy evolution, offering insights into the buildup of stellar populations across cosmic time. Understanding the intrinsic star cluster populations of dwarf galaxies is particularly important given these systems’

The Local Ultraviolet to Infrared Treasury. I. Survey Overview of the Broadband Imaging

open access: yesThe Astrophysical Journal Supplement Series
The Local Ultraviolet to Infrared Treasury (LUVIT) is a Hubble Space Telescope program that combines newly acquired data in the near-ultraviolet (NUV), optical, and near-infrared (NIR) with archival optical and NIR imaging to produce multiband ...
