SIGNATURES OF STAR CLUSTER FORMATION BY COLD COLLAPSE [PDF]
Astrophysical Journal, 2015 Subvirial gravitational collapse is one mechanism by which star clusters may form. Here we investigate whether this mechanism can be inferred from observations of young clusters.

A catalog of newly identified star clusters in GAIA DR2 [PDF]
, 2019 We present the Star cluster Hunting Pipeline (SHiP) which can identify star clusters in GAIA DR2 data, and establish a star cluster catalog for the Galactic disk. A Friend of Friend based cluster finder method is used to identify star clusters using 5-dimensional stellar parameters, $l, b, \varpi, \mu_\alpha\cos\delta$, and $\mu_\delta$.

Cluster and Double Star observations of dipolarization [PDF]
Annales Geophysicae, 2005 We studied two types of dipolarization events with different IMF conditions when Cluster and Double Star (TC-1) were located in the same local time sector: 7 August 2004, 18:00-24:00 UT, during a disturbed southward/northward IMF interval, and 14

MOCCA code for star cluster simulations – IV. A new scenario for intermediate mass black hole formation in globular clusters [PDF]
, 2015 We discuss a new scenario for the formation of intermediate mass black holes (IMBHs) in dense star clusters. In this scenario, IMBHs are formed as a result of dynamical interactions of hard binaries containing a stellar-mass black hole (BH), with other ...

Modeling Dense Star Clusters in the Milky Way and Beyond with the CMC Cluster Catalog [PDF]
Astrophysical Journal Supplement Series, 2019 We present a set of 148 independent N-body simulations of globular clusters (GCs) computed using the code CMC (Cluster Monte Carlo). At an age of ∼10–13 Gyr, the resulting models cover nearly the full range of cluster properties exhibited by the Milky ...

HENIZE 2–10: THE ONGOING FORMATION OF A NUCLEAR STAR CLUSTER AROUND A MASSIVE BLACK HOLE [PDF]
, 2015 The central region of the galaxy Henize 2–10 hosts a black hole (BH) candidate with a mass Log M BH / M ⊙ = 6.3 ± 1.1 ?> . While this putative BH does not appear to coincide with any central stellar overdensity, it is surrounded by 11 young massive ...

The Chinese ground-based instrumentation in support of the combined Cluster/Double Star satellite measurements [PDF]
Annales Geophysicae, 2005 Ground-based observations can be used to provide substantial support for Cluster/Double Star measurements and greatly enhance the mission's scientific return. There are six Chinese ground stations involved in coordinated cluster/Double Star and ground-

STAR CLUSTER FORMATION WITH STELLAR FEEDBACK AND LARGE-SCALE INFLOW [PDF]
, 2015 During star cluster formation, ongoing mass accretion is resisted by stellar feedback in the form of protostellar outflows from the low-mass stars and photo-ionization and radiation pressure feedback from the massive stars.

Massive star and star cluster formation [PDF]
Proceedings 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.
