Symmetry Breaking in Merging Binary Black Holes from Young Massive Clusters and Isolated Binaries [PDF]
Properties of the to-date observed binary black hole (BBH) merger events suggest a preference toward spin–orbit aligned mergers. Naturally, this has caused widespread interest and speculations regarding implications on various merger formation channels ...

The role of collision speed, cloud density, and turbulence in the formation of young massive clusters via cloud–cloud collisions [PDF]
Young massive clusters (YMCs) are recently formed astronomical objects with unusually high star formation rates. We propose the collision of giant molecular clouds (GMCs) as a likely formation mechanism of YMCs, consistent with the YMC conveyor-belt ...

Binary black hole mergers from young massive clusters in the pair-instability supernova mass gap [PDF]
Context. The recent discovery of the binary black hole (BBH) merger event GW190521, between two black holes (BHs) of ≈ 100 M samp , in addition to other massive BBH merger events involving BHs within the pair-instability supernova (PSN) mass gap have ...

GW190521 formation via three-body encounters in young massive star clusters [PDF]
GW190521 is the most massive binary black hole (BBH) merger observed to date, and its primary component lies in the pair-instability (PI) mass gap. Here, we investigate the formation of GW190521-like systems via three-body encounters in young massive ...

Chemical abundances of two extragalactic young massive clusters [PDF]
We use integrated-light spectroscopic observations to measure metallicities and chemical abundances for two extragalactic young massive star clusters (NGC1313-379 and NGC1705-1).

Constraining globular cluster formation through studies of young massive clusters – III. A lack of gas and dust in massive stellar clusters in the LMC and SMC [PDF]
Scenarios that invoke multiple episodes of star formation within young globular clusters (GCs) to explain the observed chemical and photometric anomalies in GCs, require that clusters can retain the stellar ejecta of the stars within them and accrete ...

LOW-VELOCITY SHOCKS TRACED BY EXTENDED SiO EMISSION ALONG THE W43 RIDGES: WITNESSING THE FORMATION OF YOUNG MASSIVE CLUSTERS [PDF]
The formation of high-mass stars is tightly linked to that of their parental clouds. Here, we focus on the high-density parts of W43, a molecular cloud undergoing an efficient event of star formation.

A comprehensive comparative test of seven widely used spectral synthesis models against multi-band photometry of young massive-star clusters [PDF]
We test the predictions of spectral synthesis models based on seven different massive-star prescriptions against Legacy ExtraGalactic UV Survey (LEGUS) observations of eight young massive clusters ...

The early evolution of young massive clusters. II. The kinematic history of NGC6618 / M17 [PDF]
The fraction of massive stars in young stellar clusters is of importance as they are the dominant sources of both mechanical and radiative feedback, strongly influencing the thermal and dynamical state of their birth environments.

The early evolution of young massive clusters. The kinematic history of NGC6611 / M16 [PDF]
In the first few Myr the massive stars dynamically interact, produce runaways and affect the initial binary population. Observing and interpreting the dynamics of young massive clusters is key to our understanding of the star formation process and ...
