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.

New Candidate Massive Clusters from 2MASS [PDF]

open access: yes, 2013
Massive stars are important for the evolution of the interstellar medium. The detailed study of their properties (such as mass loss, rotation, magnetic fields) is enormously facilitated by samples of these objects in young massive galactic star clusters.

The structure of young star clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1999
We analyse and compare the clustering of young stars in Chamaeleon I and Taurus. We compute the mean surface-density of companion stars \bar{N} as a function of angular displacement θfrom each star. We then fit \bar{N}(θ) with two simultaneous power laws.

Dynamical Mass Estimates for Two Luminous Star Clusters in Galactic Merger Remnants [PDF]

open access: yes, 2006
We present high-dispersion spectra of two extremely massive star clusters in galactic merger remnants, obtained using the UVES spectrograph mounted on the ESO Very Large Telescope.

Be stars in young clusters

open access: yesThe Astrophysical Journal, 1994
Photometric Ha and HP line indices for 71 B stars in seven galactic clusters are presented. Some stars in three of the clusters were observed at two epochs. Using these data nine Be stars were identified. Three of them were previously detected as emission-line stars, while six do not appear to have been previously recognized as such.

Star clusters as age tracers of the age-metallicity relation of the small magellanic cloud [PDF]

open access: yes, 2009
In my Thesis, I determined ages of Small Magellanic Cloud (SMC) star clusters that have formed during the galaxys entire lifetime.

HOW FAR CAN GET FRB PROGENITOR NEUTRON STARS FROM THEIR BIRTHPLACE?

open access: yesВестник. Серия физическая, 2021
The recent studies show evidence of magnetars – young neutron stars being good candidates of fast radio birth sources. Neutron stars can form as remnants of type II supernovae explosions of young stars.

The young Galactic star cluster [DBS2003] 179 [PDF]

open access: yesAstronomy & Astrophysics, 2008
Recent near- and mid-infrared surveys have brought evidence that the Milky Way continues to form massive clusters. We carry out a program to determine the basic physical properties of the new massive cluster candidate [DBS2003]179. Medium-resolution K-band spectra and deep near-infrared images of [DBS2003]179 were used to derive the spectral types of ...

Unveiling forming star clusters in the young Universe [PDF]

open access: yes, 2020
The identification of young massive star clusters (YMCs) at high redshift is becoming a real fact. We present recent results from Hubble deep imaging and VLT/ MUSE - X-Shooter observations boosted by strong gravitational lensing.
