Simulating AGN feedback in galaxy clusters with pre-existing turbulence
Jia-Lun Li, H. -Y. Karen Yang
Feedback from active galactic nuclei (AGN) is believed to play a significant role in suppressing cooling flows in cool-core (CC) clusters. Turbulence in the intracluster medium (IC…
The Discovery of 25 um Interstellar Methanol
Sarah L. Nickerson, Naseem Rangwala, Keeyoon Sung +15
We present the first astrophysical detection of methanol (CH3OH) in the torsional band near 25 um. Using high resolution mid-infrared (MIR) spectroscopy, we identified over seventy…
The impact of shear on the rotation of Galactic plane molecular clouds
Raffaele Rani, Jia-Lun Li, Toby J. T. Moore +4
Stars form in the densest regions of molecular clouds, however, there is no universal understanding of the factors that regulate cloud dynamics and their influence on the gas-to-st…
On the Interpretation of Mid-Infrared Absorption Lines of Gas-Phase HO as Observed by JWST/MIRI
Jialu Li, Adwin Boogert, Alexander G. G. M. Tielens
Ro-vibrational absorption lines of HO in the 5-8 m wavelength range selectively probe gas against the mid-infrared continuum emitting background of the inner regions of YSOs…
Dynamics in Star-forming Cores (DiSCo): Project Overview and the First Look toward the B1 and NGC 1333 Regions in Perseus
Che-Yu Chen, Rachel Friesen, Jialu Li +13
The internal velocity structure within dense gaseous cores plays a crucial role in providing the initial conditions for star formation in molecular clouds. However, the kinematic p…
