Welcome to the web site of the GALAXY AND LARGE SCALE STRUCTURE EVOLUTION (GaLSSev)
research group (Est. 2009) at Universidad de
Concepción. The main research areas of GaLSSev are galaxy
clusters and groups at all redshifts, the morphological
transformation of galaxies, and their stellar population and star formation
evolution in the history of the universe and across environments.
LATEST FEATURED RESULTS:
▲ Molecular gas properties of the
main-sequence, massive Q1700-MD94 galaxy at z~2, studied with the
NOrthern Extended Millimeter Array (NOEMA). [CI] and CO line
emission is detected and analyzed, indicating that the global
excitation properties of the molecular gas in this galaxy are
similar to those of other massive, star-forming galaxies at
similar redshift. Line modeling suggests the presence of molecular
gas with a temperature of 41 K and a density of 8 ×
103 cm-3, comparable to the high-excitation
molecular gas in main-sequence, star-forming z~1 galaxies. The
similar sizes of the CO(1-0) and CO(7-6) spatial distributions
suggest that the highly excited molecular gas is distributed
throughout the galaxy's disk and is powered by a astrong star
formation. Figure taken from
