Star formation driven by cold-flow accretion in the local Universe
The direct accretion of pristine gas streams is predicted to be the main mode of galaxy disk growth in the early universe (cold-flows). We (think we) have...
Star formation efficiency patterns in the spiral arms of M51
The distribution of ionized, molecular, and atomic hydrogen in the disk and especially along the spiral arms of the Whirlpool galaxy, M51, is investigated by...
Star Formation Histories of Ultra-faint Dwarf Galaxies: Environmental Differences between Magellanic and Non-Magellanic Satellites?
We present the color-magnitude diagrams and star formation histories (SFHs) of seven ultra-faint dwarf galaxies: Horologium 1, Hydra 2, Phoenix 2, Reticulum 2...
Star formation history for the starburst dwarf galaxy in the Local Group, IC 10
IC 10 as a starburst dwarf galaxy in the Local Group (LG) has a large population of newly formed stars that are massive and intrinsically very bright in...
Star Formation History of Two Fields in the Halo of NGC 5128
NGC 5128 galaxy is a giant elliptical galaxy located in the Centaurus group of galaxies at 3.8 Mpc. We aim to study the star formation history (SFH) of two...
Star formation in outer rings of S0 galaxies. V. UGC 4599: An S0 with gas probably accreted from a filament
Aims: Though S0 galaxies are usually thought to be `red and dead', they often demonstrate weak star formation organised in ring structures and located in their...
An analysis of the IRAS data for a sample of classical (optically selected) Seyfert galaxies is presented. The IRAS fluxes at 25 micron, 60 micron, and 100...
An analysis of IRAS data for a sample of classical (optically selected) Seyfert galaxies is presented. The IRAS fluxes at 25, 60, and 100 μm are found to be...
