The ALMA Survey of 70 μm Dark High-mass Clumps in Early Stages (ASHES). X. Hot Gas Reveals Deeply Embedded Star Formation

Massive infrared dark clouds (IRDCs) are considered to host the earliest stages of high-mass star formation. In particular, 70 μ m dark IRDCs are the colder and more quiescent clouds. At a scale of about 5000 au using formaldehyde (H _2 CO) emission, we investigate the kinetic temperature of dense c...
