Spectroscopic study of globular and fuzzy clusters in Lenticular galaxy NGC 1023
Miguel A. López-Santamaría, Y. D. Mayya, Luis Lomelí-Núñez +5
We here report the results from spectroscopic observations of a sample of 26 globular cluster (GC) and 21 faint fuzzy (FF) candidates in the lenticular galaxy NGC 1023 using the 10…
Detection and characterization of detached tidal dwarf galaxies
Javier Zaragoza-Cardiel, Beverly J. Smith, Mark G. Jones +7
Tidal interactions between galaxies often give rise to tidal tails, which can harbor concentrations of stars and interstellar gas resembling dwarf galaxies. Some of these tidal dwa…
Ages and metallicities of globular clusters in M81 using GTC/OSIRIS spectra
Luis Lomelí-Núñez, Y. D. Mayya, L. H. Rodríguez-Merino +8
We here present the results of an analysis of the optical spectroscopy of 42 globular cluster (GC) candidates in the nearby spiral galaxy M81 (3.61~Mpc). The spectra were obtained…
Constraints on star formation in Orion A from Gaia
Jairo A. Alzate, Gustavo Bruzual, Marina Kounkel +4
We develop statistical methods within a Bayesian framework to infer the star formation history from photometric surveys of pre-main sequence populations. Our procedures include cor…
The stellar population responsible for a kiloparsec size superbubble seen in the JWST "phantom" images of NGC628
Y. D. Mayya, J. A. Alzate, L. Lomelí-Núñez +11
We here study the multi-band properties of a kiloparsec-size superbubble in the late-type spiral galaxy NGC628. The superbubble is the largest of many holes seen in the early relea…
Star cluster survival in dark matter halos: An old cluster in Eridanus II?
Jairo A. Alzate, Verónica Lora, Gustavo Bruzual +2
The star formation history and the internal dynamics of Milky Way satellite galaxies are often complicated. In the last years, a substantial fraction of the known faint dwarf satel…
Star formation history of the solar neighbourhood as told by Gaia
Jairo A. Alzate, Gustavo Bruzual, Daniel J. Díaz-González
The Gaia DR2 catalog is the best source of stellar astrometric and photometric data available today. The history of the Milky Way galaxy is written in stone in this data set. Paral…
