The growth channel of massive galaxies involving mergers can be studied via close pairs as putative merger progenitors, where the stellar populations of the...
Assessing the accuracy of star formation rate measurements by direct star count in molecular clouds
Star formation estimates based on the counting of young stellar objects (YSOs) are commonly carried out for nearby star-forming regions in the Galaxy, and in...
Association of cold gas, massive galaxies, and AGNs in a filamentary protocluster traced by triple narrow-band imaging
We investigate galaxy populations in the HS 1700+64 protocluster at $z=2.30$, characterized by two prominent linear filaments traced by spatially extended ${\rm...
Astrometry and photometry of stars and star clusters in M33
We present positions and magnitudes of stars and star clusters in a 1° × 1° area centered on M33. The survey is based on deep archival ground-based images using...
Astronomers discover that the first galaxies had very different shapes to today's galaxies
Thanks to images obtained by the James Webb Telescope (JWST), an international scientific team in which the Instituto de Astrofísica de Canarias (IAC)...
Astronomers discover tiny galaxy with extraordinary star formation in distant Universe
Using first-of-their-kind observations from the James Webb Space Telescope (JWST), an international scientific team, in which the Instituto de Astrofísica de...
Astronomers find a galaxy unchanged since the early universe
Researchers at the Instituto de Astrofísica de Canarias (IAC) confirm the first detection of a relic galaxy with the Hubble Space Telescope. The results of this...
Astronomers find the first galaxy whose ultraviolet luminosity is comparable to that of a quasar
An international scientific team, led by researchers at the Centre for Astrobiology (CAB, CSIC-INTA) and with participation by the Instituto de Astrofísica de...
ASW<SUP>2</SUP>DF: Census of the obscured star formation in a galaxy cluster in formation at z = 2.2
We report the results of the deep and wide Atacama Large Millimeter/submillimeter Array (ALMA) 1.2 mm mapping of the Spiderweb protocluster at z = 2.16. The...
