Submillimeter and millimeter wavelengths provide a unique view of the Universe, from the gas and dust that fills and surrounds galaxies to the chromosphere of our own Sun. Current single-dish facilities have presented a tantalising view of the bright

Cloud properties across spatial scales in simulations of the interstellar medium

Molecular clouds (MC) are structures of dense gas in the interstellar medium (ISM), that extend from ten to a few hundred parsecs and form the main gas reservoir available for star formation. Hydrodynamical simulations of varying complexity are a pro

On the Scarcity of Dense Cores ($n>10^{5}$ cm$^{-3}$) in High Latitude Planck Galactic Cold Clumps

High-latitude ($|b|>30^{\circ}$) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that target high-latitude Pla

ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): Discovery of an extremely dense and compact object embedded in the prestellar core G208.68-19.92-N2

Autor: Hirano, Naomi, Sahu, Dipen, Liu, Sheng-Yaun, Liu, Tie, Tatematsu, Ken'ichi, Dutta, Somnath, Li, Shanghuo, Lee, Chin-Fei, Li, Pak Shing, Hsu, Shih-Ying, Lin, Sheng-Jun, Johnstone, Doug, Bronfman, Leonardo, Chen, Huei-Ru Vivien, Eden, David J., Kuan, Yi-Jehng, Kwon, Woojin, Lee, Chang Won, Liu, Hong-Li, Rawlings, Mark G., Ristorcelli, Isabelle, Traficante, Alessio

The internal structure of the prestellar core G208.68-19.02-N2 (G208-N2) in the Orion Molecular Cloud 3 (OMC-3) region has been studied with the Atacama Large Millimeter/submillimeter Array (ALMA). The dust continuum emission revealed a filamentary s

Star cluster progenitors are dynamically decoupled from their parent molecular clouds

Autor: Peretto, Nicolas, Rigby, Andrew J., Louvet, Fabien, Fuller, Gary A., Traficante, Alessio, Gaudel, Mathilde

The formation of stellar clusters dictates the pace at which galaxies evolve, and solving the question of their formation will undoubtedly lead to a better understanding of the Universe as a whole. While it is well known that star clusters form withi
