Dust-buried Compact Sources in the Dwarf Galaxy NGC 4449

open access: yesThe Astrophysical Journal, 2023
Multiwavelength images from the Hubble Space Telescope covering the wavelength range 0.27–1.6 μ m show that the central area of the nearby dwarf galaxy NGC 4449 contains several tens of compact sources that are emitting in the hydrogen recombination line

Young Massive Star Clusters [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2010
Young massive clusters (YMCs) are dense aggregates of young stars that form the fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy and the Local Group, but they are particularly abundant in starburst and interacting galaxies.

Young Star Clusters: Progenitors of Globular Clusters!? [PDF]

open access: yesHighlights of Astronomy, 2005
AbstractStar cluster formation is a major mode of star formation in the extreme conditions of interacting galaxies and violent starbursts. Young clusters are observed to form in a variety of such galaxies, a substantial number resembling the progenitors of globular clusters in mass and size, but with significantly enhanced metallicity.

The Cosmic Merger Rate Density Evolution of Compact Binaries Formed in Young Star Clusters and in Isolated Binaries [PDF]

open access: yesAstrophysical Journal, 2020
Next generation ground-based gravitational-wave detectors will observe binary black hole (BBH) mergers up to redshift , probing the evolution of compact binary (CB) mergers across cosmic time.

Kinematics in Young Star Clusters and Associations with Gaia DR2 [PDF]

open access: yesAstrophysical Journal, 2018
The Gaia mission has opened a new window into the internal kinematics of young star clusters at the sub-km s−1 level, with implications for our understanding of how star clusters form and evolve.

Young Star Clusters in the LMC [PDF]

open access: yesSymposium - International Astronomical Union, 1991
We discuss the integrated colours, kinematics, formation, dynamical evolution and initial mass functions of the young globular star clusters in the Large Magellanic Cloud (LMC). Because these clusters are so young, they offer us insights, unobtainable from the old globular clusters in our Galaxy, into the formation and early dynamical evolution of ...

Merging black holes in young star clusters [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
Searching for distinctive signatures, which characterize different formation channels of binary black holes (BBHs), is a crucial step towards the interpretation of current and future gravitational wave detections.

Intermediate-mass Black Holes from High Massive-star Binary Fractions in Young Star Clusters [PDF]

open access: yesAstrophysical Journal, 2020
Black holes formed in dense star clusters, where dynamical interactions are frequent, may have fundamentally different properties than those formed through isolated stellar evolution.

Be Stars in Young LMC Clusters [PDF]

open access: yesSymposium - International Astronomical Union, 1994
Slitless field Hα spectroscopy with a resolution of 0.2 nm has detected numerous Be stars in 3 young open star clusters in the LMC but only a few each in one Galactic and one LMC cluster. The line widths indicate rapid rotation as is typical of Galactic field Be stars.

Binary black holes in young star clusters: the impact of metallicity [PDF]

open access: yes, 2020
Young star clusters are the most common birth-place of massive stars and are dynamically active environments. Here, we study the formation of black holes (BHs) and binary black holes (BBHs) in young star clusters, by means of 6000 N-body simulations ...
