The ALMA Survey of 70 m Dark High-mass Clumps in Early Stages (ASHES). IX. Physical Properties and Spatial Distribution of Cores in IRDCs
Kaho Morii, Patricio Sanhueza, Fumitaka Nakamura +13
The initial conditions found in infrared dark clouds (IRDCs) provide insights on how high-mass stars and stellar clusters form. We have conducted high-angular resolution and high-s…
The ALMA Survey of 70 Dark High-mass Clumps in Early Stages (ASHES). VII: Chemistry of Embedded Dense Cores
Shanghuo Li, Patricio Sanhueza, Xing Lu +15
We present a study of chemistry toward 294 dense cores in 12 molecular clumps using the data obtained from the ALMA Survey of 70 dark High-mass clumps in Early Stages (ASH…
The ALMA Survey of 70 m Dark High-mass Clumps in Early Stages (ASHES). V. Deuterated Molecules in the 70 m dark IRDC G14.492-00.139
Takeshi Sakai, Patricio Sanhueza, Kenji Furuya +14
We have observed the 70 m dark infrared dark cloud (IRDC) G14.492-00.139 in the ND =3--2, DCO =3--2, DCN =3--2, and CO =2--1 lines, using the Atac…
The ALMA Survey of 70 m Dark High-mass Clumps in Early Stages (ASHES). IV. Star formation signatures in G023.477
Kaho Morii, Patricio Sanhueza, Fumitaka Nakamura +15
With a mass of 1000 and a surface density of 0.5 g cm, G023.477+0.114 also known as IRDC 18310-4 is an infrared dark cloud (IRDC) that has the potentia…
Gravity Driven Magnetic Field at ~1000 au Scales in High-mass Star Formation
Patricio Sanhueza, Josep Miquel Girart, Marco Padovani +20
A full understanding of high-mass star formation requires the study of one of the most elusive components of the energy balance in the interstellar medium: magnetic fields. We repo…
The ALMA Survey of 70m Dark High-mass Clumps in Early Stages (ASHES) III. A Young Molecular Outflow Driven by a Decelerating Jet
Daniel Tafoya, Patricio Sanhueza, Qizhou Zhang +12
We present a spatio-kinematical analysis of the CO~(=21) line emission, observed with the Atacama Large Millimter/submillimter Array (ALMA), of the outflow associat…
Digging into the Interior of Hot Cores with ALMA (DIHCA). I. Dissecting the High-mass Star-Forming Core G335.579-0.292 MM1
Fernando A. Olguin, Patricio Sanhueza, Andrés E. Guzmán +10
We observed the high-mass star-forming region G335.579-0.292 with the Atacama Large Millimeter/submillimeter Array (ALMA) at 226 GHz with an angular resolution of 0.3'' ($\sim 1000…
Galaxy mergers up to z < 2.5 II: AGN incidence of merging galaxies at separations of 3-15 kpc
Andrea Silva, Danilo Marchesini, John D. Silverman +4
We present a study of the incidence of active galactic nucleus (AGN) in a sample of major merging systems at 0.3<z<2.5. Galaxies in this merger sample have projected separations be…
