Young massive clusters (YMCs) with stellar masses of 104–105 M☉ and core stellar densities of 104–105 stars per cubic pc are thought to be the “missing link” between open clusters and extreme extragalactic super star clusters and globular clusters. As such, studying the initial conditions of YMCs offers an opportunity to test cluster formation models across the full cluster mass range. G0.253 + 0.016 is an excellent candidate YMC progenitor. We make use of existing multi-wavelength data… 

THE GALACTIC CENTER CLOUD G0.253+0.016: A MASSIVE DENSE CLOUD WITH LOW STAR FORMATION POTENTIAL

We present the first interferometric molecular line and dust emission maps for the Galactic Center (GC) cloud G0.253+0.016, observed using CARMA and the SMA. This cloud is very dense, and

STAR FORMATION IN THE MASSIVE “STARLESS” INFRARED DARK CLOUD G0.253+0.016

G0.253+0.016 is a remarkable massive infrared dark cloud located within ∼100 pc of the galactic center. With a high mass of 1.3 × 105 M☉, a compact average radius of ∼2.8 pc, and a low dust

G0.253+0.016: A CENTRALLY CONDENSED, HIGH-MASS PROTOCLUSTER

Despite their importance as stellar nurseries and the building blocks of galaxies, very little is known about the formation of the highest mass clusters. The dense clump G0.253+0.016 represents an

We present near-infrared spectroscopy and 1 mm line and continuum observations of a recently identified site of high mass star formation likely to be located in the Central Molecular Zone (CMZ) near

Evidence that widespread star formation may be underway in G0.253+0.016, ‘The Brick’

Image cubes of differential column density as a function of dust temperature are constructed for Galactic Centre molecular cloud G0.253+0.016 ('The Brick') using the recently described PPMAP

Young massive star cluster formation in the Galactic Centre is driven by global gravitational collapse of high-mass molecular clouds

Young massive clusters (YMCs) are the most compact, high-mass stellar systems still forming at the present day. The precursor clouds to such systems are, however, rare due to their large initial gas
