PublicationAsymptotic giant branch stars in NGC 6822: Probes of star formation history
About 500 asymptotic giant branch (AGB) stars have been resolved and photometrically measured in the Local Group (LG) dwarf irregular galaxy NGC 6822. They draw...
TalkBar characterization from S4G imaging: Gaining insight into the secular evolution of disc galaxies
The ΛCDM model predicts that galaxies originate in dark matter haloes, undergoing in their early age a process of continuous merges with other galaxies that...
PublicationCCD photometry of resolved dwarf irregular galaxies. I - Sextans A
CCD UBV photometry of 2279 stars in Sextans A is presented. Differences with the photometric scales of Sandage and Carlson (1985) and Hoessel et al. (1983) are...
PublicationCCD photometry of resolved dwarf irregular galaxies. II - DDO 187. III - GR 8
CCD photometry of resolved dwarf irregular galaxies was obtained with the 4-m Cerro Tololo Interamerican Observatory telescope in February 1985. BV data from 77...
PublicationCEERS Key Paper. III. The Diversity of Galaxy Structure and Morphology at z = 3-9 with JWST
We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z = 3-9 using early James...
PublicationExpectations of the Size Evolution of Massive Galaxies at 3 ≤ z ≤ 6 from the TNG50 Simulation: The CEERS/JWST View
We present a catalog of about 25,000 images of massive (M ⋆ ≥ 109 M ⊙) galaxies at redshifts 3 ≤ z ≤ 6 from the TNG50 cosmological simulation, tailored for...
PublicationH II regions in Sextans A
CCD narrow-band H-alpha photometry of the Sextans A Local Group dwarf irregular galaxy is presented. Fourteen H II regions have been recorded. Their...
PublicationInfrared studies of Seyfert galaxies and of the irregular galaxy M 82
Middle and far infrared studies of the irregular galaxy M 82 and of Seyfert galaxies are presented. M 82 was observed spectrophotometrically from 8 to 13...
