Bar Formation in Milky Way type Galaxies
Open Astronomy, 2016 Many barred galaxies, possibly including the Milky Way, have cusps in their centers. There is a widespread belief, however, that the usual bar instability, which occurs in bulgeless galaxy models, is impossible for cuspy models because of the presence of

The Astrophysical Journal, 2023 We investigate the role of halo concentration in the formation of intracluster light (ICL) in galaxy groups and clusters, as predicted by a state-of-the-art semianalytic model of galaxy formation, coupled with a set of high-resolution dark-matter-only ...

The Origin of Star Formation in Early-type Galaxies Inferred from Spatially Resolved Spectroscopy
The Astrophysical Journal, 2023 We investigate the origin of star formation activity in early-type galaxies with current star formation using spatially resolved spectroscopic data from the Mapping Nearby Galaxies at Apache Point Observatory in the Sloan Digital Sky Survey (SDSS).

The Astrophysical Journal, 2023 We present kinematics of six local extremely metal-poor galaxies (EMPGs) with low metallicities (0.016–0.098 Z _⊙ ) and low stellar masses (10 ^4.7 –10 ^7.6 M _⊙ ).

Joint galaxy–galaxy lensing and clustering constraints on galaxy formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We compare predictions for galaxy–galaxy lensing profiles and clustering from the Henriques et al. public version of the Munich semi-analytical model (SAM) of galaxy formation and the IllustrisTNG suite, primarily TNG300, with observations from KiDS + GAMA and SDSS-DR7 using four different selection functions for the lenses ...

The Astrophysical Journal, 2023 We study the spatially resolved stellar populations of 444 galaxies at 0.3 < z < 6.0 in two clusters (WHL 0137–08 and MACS 0647+70) and a blank field, combining imaging data from the Hubble Space Telescope and JWST to perform spatially resolved spectral ...

Two-phase galaxy formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We propose and test a scenario for the assembly and evolution of luminous matter in galaxies which substantially differs from that adopted by other semianalytic models. As for the dark matter (DM), we follow the detailed evolution of halos within the canonical LCDM cosmology using standard Montecarlo methods.

Galaxy Formation: Isocam Counts [PDF]
Symposium - International Astronomical Union, 1996 Detailed observations in the optical do not allow to discriminate between the following scenarii of galaxy formation: - synchronous formation at large redshift (z > 7). - hierarchical merging, down to z ≤ 1, of proto-galactic lumps formed at very high redshift (≈ 10).

The Astrophysical Journal, 2023 We use the DR9 of the DESI legacy imaging survey and SDSS galaxy groups to measure the conditional luminosity function (CLF) for groups with halo mass M _h ≥ 10 ^12 M _⊙ and redshift 0.01 ≤ z ≤ 0.08, down to a limiting r -band magnitude of M _r = −10 to −
