Post-doctoral fellowship for one year on Integrated light of globular clusters

Project title: Integrated light of Extragalactic globular clusters

Institution: IAG/USP

Post-Doctoral Fellowship fromm FAPESP

Duration: 1 year

 Abstract:

The spectroscopic study of faint globular clusters can be carried out in two
ways: for the relatively faint clusters, it is possible to carry out low to
medium-resolution
spectroscopy of individual stars, and for more distant ones, for which
there is no possibility of distinguishing individual stars, it is possible
to study their integrated spectra, as carried out in our group
(e.g. Martins et al. 2019; Moura et al. 2019).

 Objectives:

Globular clusters have typical integrated magnitudes in the range -6 <
MV < -8, that is about 5 magnitudes brighter than an individual red giant branch (RGB) star.
For a given apparent magnitude, such globular clusters are thus observable at a 10 times
greater distance compared to the brightest RGB stars, which corresponds to a factor of
1000 in the accessible volume of space.

The aims are twofold: the study of extragalactic globular clusters, and the
combination of single stellar populations so-computed for the study of
the integrated spectra of galaxies.
