Stellar content of NGC 404 - The nearest S0 Galaxy
We report V -band and I -band CCD stellar and surface photometry of the galaxy NGC 404 , taken with HST WFPC2 and the 2.5 m Nordic telescope. The colour...
Stellar content, planetary nebulae, and globular clusters of [KKS2000]04 (NGC 1052-DF2)
[KKS2000]04 (NGC 1052-DF2) has become a controversial and well-studied galaxy after the claims suggesting a lack of dark matter and the presence of an...
Stellar disc truncations and extended haloes in face-on spiral galaxies
We use data from the IAC Stripe82 Legacy Project to study the surface photometry of 22 nearby, face-on to moderately inclined spiral galaxies. The reprocessed...
Stellar dynamics of blue compact galaxies. II. Further indications of a merger in ESO 338-IG04
Context: Luminous blue compact galaxies, common at z ~ 1 but now relatively rare, show disturbed kinematics in emission lines. Aims: As part of a programme to...
We have calculated a grid of empirically well tested evolutionary tracks with masses M between 0.5 and 50Msolar, spaced by approximately 0.1 in log M, and with...
Stellar feedback and the energy budget of late-type Galaxies: missing baryons and core creation
In a ΛCDM cosmology, galaxy formation is a globally inefficient process: it is often the case that far fewer baryons are observed in galaxy discs than expected...
Taking advantage of the ultradeep near-infrared imaging obtained with the Hubble Space Telescope on the Hubble Ultra Deep Field, we detect and explore for the...
