Series: Astronomy Colloquium
Date: Wednesday 26-Sep-2018
Time: 16:05-17:00 (4:05-5:00)
Location: ATL 2400
Speaker: Dr. Sebastian Sanchez (Instituto de Astronomia Universidad Nacional Autonoma de Mexico)
Title: The kiloparsec scale in galaxies: clues about their evolution
Galaxies were spatially resolved even before they were known to be galaxies. Despite this fact, we still study their evolution as if they were unresolved objects. The advent of large photometric and spectroscopic galaxy surveys (like 2dF,SDSS,GAMA), which supplied us with integrated or average properties of hundred of thousand or million of objects, have reinforced this approach to understand galaxy evolution. In more recent times, however, Integral Field Spectroscopy techniques opened a new window to the statistical exploration of galaxy properties, spatially resolved, at a kiloparsec scale.
I summarize here the sate-of-the-art of IFS galaxy surveys, highlighting some of their main results. In particular I will focus on the exploration of well-known scaling/evolutionary relations (such as the SK, SFMS and MZ-relations), which have their physical origin in the their kiloparsec-scale counterparts, and discuss their implications.
Colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer. Lunch will normally be reserved for the speaker to talk to graduate students.
