PHANGS: constraining star formation time-scales using the spatial correlations of star clusters and giant molecular clouds

open access: yes, 2023
In the hierarchical view of star formation, giant molecular clouds (GMCs) undergo fragmentation to form small-scale structures made up of stars and star clusters.

Redshift distribution of gamma-ray bursts and star formation rate [PDF]

open access: yes, 2006
Aims. The redshift distribution of gamma-ray bursts collected in the BATSE Catalog is compared with the star formation rate.We aim to clarify the accordance between them. We also study the case of comoving number density of bursts monotonously increasing

Massive star and star cluster formation [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
AbstractI review the status of massive star formation theories: accretion from collapsing, massive, turbulent cores; competitive accretion; and stellar collisions. I conclude the observational and theoretical evidence favors the first of these models.

Gas, star formation and quenching in galaxy clusters and groups [PDF]

open access: yes, 2019
I will review our current knowledge of the link between the star formation activity+quenching and the gas availability and removal as a function of galaxy environment focusing on galaxy clusters and groups.

Modeling Two First Hydrostatic Core Candidates Barnard 1b-N and 1b-S

open access: yesThe Astrophysical Journal, 2023
A first hydrostatic core (FHC) is proposed to form after the initial collapse of a prestellar core, as a seed of a Class 0 protostar. FHCs are difficult to observe because they are small, compact, embedded, and short lived.

Dust transport in envelopes of disk-embedded planets

open access: yesAstronomy & Astrophysics
Planets embedded in protoplanetary disks accrete solids through their gaseous envelopes. The spatial distribution of these dust particles inside the envelopes of disk-embedded planets is poorly known.

Triple Spiral Arms of a Triple Protostar System Imaged in Molecular Lines

open access: yesThe Astrophysical Journal, 2023
Most stars form in multiple-star systems. For a better understanding of their formation processes, it is important to resolve the individual protostellar components and the surrounding envelope and disk material at the earliest possible formation epoch ...

The volumetric star formation law in nearby galaxies [PDF]

open access: yes, 2022
Star formation laws are empirical relations between the cold gas (HI+H$_2$) content of a galaxy and its star formation rate (SFR), being crucial for any model of galaxy formation and evolution.

Star clusters in unperturbed spiral galaxies [PDF]

open access: yes, 2008
Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.
