Historical Perspectives on the Concept of Galaxy Size
A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these...
Images from the Hubble Space Telescope and GRANTECAN help to show how the first galaxies were formed
One of the most interesting questions for astrophysicists for the past few decades is how and when did the first galaxies form. One of the possible answers to...
JWST/NIRCam Narrowband Survey of Paβ Emitters in the Spiderweb Protocluster at z = 2.16
We report the initial result of our Paβ narrowband imaging on a protocluster with the JWST Near Infrared Camera (NIRCam). As NIRCam enables deep narrowband...
Local and Global Gas Metallicity versus Stellar Age Relation in MaNGA Galaxies
The search for new global scaling relations linking the physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially...
MIGHTEE-HI: Evolution of HI Scaling Relations of Star-forming Galaxies at z < 0.5
We present the first measurements of H I galaxy scaling relations from a blind survey at z > 0.15. We perform spectral stacking of 9023 spectra of star-forming...
On the Nature of Disks at High Redshift Seen by JWST/CEERS with Contrastive Learning and Cosmological Simulations
Visual inspections of the first optical rest-frame images from JWST have indicated a surprisingly high fraction of disk galaxies at high redshifts. Here, we...
We describe the Milky Way Survey (MWS) that will be undertaken with the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4 m telescope at the Kitt Peak...
Public talk: The Milky Way and its impacts with other galaxies
Tomorow, 10th November, at 18:00 the Museum of Science and the Cosmos will offer, free, a lectura with the title “The Milky Way and its encounters with other...
