S4G: The Spitzer Survey of Stellar Structure in Galaxies
Galaxies are the basic building blocks of the Universe, and understanding their formation and evolution is crucial to many areas of current astrophysical...
The realism of hydrodynamical simulations of the formation and evolution of galaxies has improved considerably in recent years. I will try to give some insight...
Spectroscopic Confirmation of CEERS NIRCam-selected Galaxies at z ≃ 8-10
We present JWST/NIRSpec prism spectroscopy of seven galaxies selected from Cosmic Evolution Early Release Science (CEERS) survey NIRCam imaging with photometric...
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 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-forming galaxies in SDSS: signs of metallicity evolution
Evolution of galaxies through cosmic time has been widely studied at high redshift, but there are a few studies in this field at lower redshifts.However, low...
Taking advantage of the ultra-deep near-infrared imaging obtained with the Hubble Space Telescope on the Hubble Ultra Deep Field, we detect and explore for the...
Different components of galaxies are the result of internal and environmental processes during their lifetimes. Disentangling these processes is an important...
Synergies from a joint analysis of photometry, spectroscopy and morphology of early-type galaxies in MaNGA
Stellar populations vary across the galaxy population. However, even within a single galaxy, there are stellar population gradients which spatially resolved...
