The AGORA high-resolution galaxy simulations comparison project: Public data release
Santi Roca-Fàbrega, Ji-hoon Kim, Joel R. Primack +11
As part of the AGORA High-resolution Galaxy Simulations Comparison Project (Kim et al. 2014, 2016) we have generated a suite of isolated Milky Way-mass galaxy simulations using 9 s…
Core Emergence in a Massive Infrared Dark Cloud: A Comparison Between Mid-IR Extinction and 1.3 mm Emission
Shuo Kong, Jonathan C. Tan, Héctor G. Arce +3
Stars are born from dense cores in molecular clouds. Observationally, it is crucial to capture the formation of cores in order to understand the necessary conditions and rate of th…
Kiloparsec-Scale Simulations of Star Formation in Disk Galaxies. IV. Regulation of Galactic Star Formation Rates by Stellar Feedback
Michael J. Butler, Jonathan C. Tan, Romain Teyssier +3
Star formation from the interstellar medium of galactic disks is a basic process controlling the evolution of galaxies. Understanding the star formation rate in a local patch of a…
Zooming in to Massive Star Birth
Shuo Kong, Jonathan C. Tan, Paola Caselli +3
We present high resolution (0.2", 1000 AU) 1.3 mm ALMA observations of massive infrared dark cloud clump, G028.37+00.07-C1, thought to harbor the early stages of massive star forma…
The AGORA High-Resolution Galaxy Simulations Comparison Project. II: Isolated Disk Test
Ji-hoon Kim, Oscar Agertz, Romain Teyssier +40
Using an isolated Milky Way-mass galaxy simulation, we compare results from 9 state-of-the-art gravito-hydrodynamics codes widely used in the numerical community. We utilize the in…
Mid-J CO Shock Tracing Observations of Infrared Dark Clouds III: SLED fitting
A. Pon, M. J. Kaufman, D. Johnstone +6
Giant molecular clouds contain supersonic turbulence that can locally heat small fractions of gas to over 100 K. We run shock models for low-velocity, C-type shocks propagating int…
The Distribution of Mass Surface Densities in a High-Mass Protocluster
Wanggi Lim, Jonathan C. Tan, Jouni Kainulainen +2
We study the probability distribution function (PDF) of mass surface densities, , of infrared dark cloud (IRDC) G028.37+00.07 and its surrounding giant molecular cloud. This PDF…
An Ordered Bipolar Outflow from a Massive Early-Stage Core
Jonathan C. Tan, Shuo Kong, Yichen Zhang +3
We present ALMA follow-up observations of two massive, early-stage core candidates, C1-N & C1-S, in Infrared Dark Cloud (IRDC) G028.37+00.07, which were previously identified by th…
Mid-J CO shock tracing observations of infrared dark clouds II Low-J CO constraints on excitation, depletion, and kinematics
A. Pon, D. Johnstone, P. Caselli +6
Infrared dark clouds are kinematically complex molecular structures in the interstellar medium that can host sites of massive star formation. We present 4 square arcminute maps of…
The Deuterium Fraction in Massive Starless Cores and Dynamical Implications
Shuo Kong, Jonathan C. Tan, Paola Caselli +6
We study deuterium fractionation in two massive starless/early-stage cores C1-N and C1-S in Infrared Dark Cloud (IRDC) G028.37+00.07, first identified by Tan et al. (2013) with ALM…
Mid-J CO Shock Tracing Observations of Infrared Dark Clouds I
A. Pon, P. Caselli, D. Johnstone +5
Infrared dark clouds (IRDCs) are dense, molecular structures in the interstellar medium that can harbour sites of high-mass star formation. IRDCs contain supersonic turbulence, whi…
The Dynamics of Massive Starless Cores with ALMA
Jonathan C. Tan, Shuo Kong, Michael J. Butler +2
How do stars that are more massive than the Sun form, and thus how is the stellar initial mass function (IMF) established? Such intermediate- and high-mass stars may be born from r…
Kiloparsec-Scale Simulations of Star Formation in Disk Galaxies. I. The unmagnetized and zero-feedback limit
Sven Van Loo, Michael J. Butler, Jonathan C. Tan
We present hydrodynamic simulations of the evolution of self-gravitating dense gas on scales of 1 kiloparsec down to < parsec in a galactic disk, designed to study dense clump form…
Kiloparsec-Scale Simulations of Magnetised Molecular Clouds in Disk Galaxies
Sven Van Loo, Michael J. Butler, Jonathan C. Tan +1
We present simulations of the evolution of self-gravitating dense gas on kiloparsec-size scales in a galactic disk, designed to study dense clump formation from giant molecular clo…
A Virialized Filamentary Infrared Dark Cloud
Audra K. Hernandez, Jonathan C. Tan, Jouni Kainulainen +4
The initial conditions of massive star and star cluster formation are expected to be cold, dense and high column density regions of the interstellar medium, which can reveal themse…
Mapping Large-Scale CO Depletion in a Filamentary Infrared Dark Cloud
Audra K. Hernandez, Jonathan C. Tan, Paola Caselli +4
Infrared Dark Clouds (IRDCs) are cold, high mass surface density and high density structures, likely to be representative of the initial conditions for massive star and star cluste…
