To decipher the underlying processes that shape galaxies over time, we need to uncover their physical properties and the conditions controlling them. This in turn requires in-depth measurements of the stars, gas and dust, inside as well as surrounding the galaxies. Continua a leggere A 3D View on Galaxy Evolution
Both black hole accretion and galaxy formation and evolution are important research topics in astrophysics. They focus on quite different scales and both have been intensively studied.
The purpose of the workshop is to share the recent advances in strong lensing and discuss the future directions with current/upcoming facilities and wide-field surveys. Topics at the workshop include dark matter substructures, galaxy evolution, time-delay cosmology, galaxy clusters, high-z galaxies, simulations, and strong lens searches.
The study of stellar populations is one of the most relevant diagnostics to constrain galaxy formation and evolution. Quantitative analyses of the stellar content of stellar systems pave the way to `convert’ starlight into physical quantities like stellar masses, chemical abundances and star formation rates, and to trace back in time the evolution and the chemical enrichment history of galaxies.

In celebration of Alan Dressler’s illustrious career, Carnegie Observatories is pleased to be holding a four day workshop covering current topics in galaxy evolution. The workshop will be held in Springdale, Utah at the gateway to Zion National Park. The workshop schedule will provide ample opportunities for discussion and for participants to explore the park.

During the Evolution 2014 Workshop four central themes in the field of galaxy evolution will be explored by bringing together current and future studies with ALMA and from across the electromagnetic spectrum from existing (e.g. VLA/GBT/IRAM/CARMA, HST, Spitzer/Herschel, Chandra/NuStar) as well as future facilities (e.g., JWST, MeerKAT/ASKAP/SKA, LSST, EUCLID, TMT/GMT/EELT, CCAT/LMT).

Over the last years, IR Extragalactic Astronomy has made rapid progress thanks to major survey efforts carried out with ground-based and space observatories. These studies are preparing the ground for the science to be tackled with the next generation of IR telescopes, in particular the James Webb Space Telescope (JWST).

2014 will represent 60 years since the optical identification of Cygnus A (Baade & Minkowski, 1954) as an extra-galactic source and the first powerful active galactic nucleus. Since then, powerful AGN have been identified across the electromagnetic spectrum and in galaxies from the local Universe up to z~7.

Located some 75.000 light years from us, a galaxy known as Segue 1 has some unusual properties: it is the faintest galaxy ever detected. It is very small, containing only about 1.000 stars. And it has a rare chemical composition, with vanishingly small amounts of metallic elements present.
New Herschel Space Observatory findings have given scientists a remarkable insight into the internal dynamics of two young galaxies. Surprisingly, they have shown that just a few billion years after the Big Bang, some galaxies were rotating in a mature way, seemingly having completed the accumulation of their gas reservoirs.
