Massive Star Formation Starts in Sub-virial Dense Clumps Unless Resisted by Strong Magnetic Fields

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Yueluo Wang, Fengwei Xu, , | Summary: The initial conditions are critical for understanding high-mass star formation, but are not well observed. Built on our previous characterization of a Galaxy-wide sample of 463 candidate high-mass starless clumps (HMSCs), here we investigate the dynamical state of […]

Parameter constraints for accreting millisecond pulsars with synthetic NICER data

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Bas Dorsman, Tuomo Salmi, Anna L. Watts, Mason Ng, Satish Kamath | Summary: Pulse profile modelling (PPM) is a technique for inferring mass, radius and hotspot properties of millisecond pulsars. PPM is now regularly used for analysis of rotation-powered millisecond pulsars (RMPs) with data from the Neutron […]

Extremely Dense Gas around Little Red Dots and High-redshift Active Galactic Nuclei: A Non-stellar Origin of the Balmer Break and Absorption Features

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Roberto Maiolino, , , | Summary: The James Webb Space Telescope (JWST) has uncovered low-luminosity active galactic nuclei (AGNs) at high redshifts of $zgtrsim 4-7$, powered by accreting black holes (BHs) with masses of $sim 10^{6-8}~M_odot$. One remarkable distinction of these JWST-identified AGNs, compared to […]

Enhancing Direct Detection of Higgsino Dark Matter

Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, Samuel S. Y. Wong, , | Summary: While much supersymmetric weakly interacting massive particle (WIMP) parameter space has been ruled out, one remaining important candidate is Higgsino dark matter. The Higgsino can naturally realize the "inelastic dark matter" scenario, where the […]

A STING-CASM-GABARAP Pathway Activates LRRK2 at Lysosomes

Kavli Affiliate: Shawn Ferguson | Authors: Amanda Bentley-DeSousa and Shawn Ferguson | Summary: Mutations that increase LRRK2 kinase activity have been linked to Parkinson’s disease and Crohn’s disease. LRRK2 is also activated by lysosome damage evoked by chemical and pathogenic stimuli. However, the endogenous cellular mechanisms that control LRRK2 kinase activity are not well understood. […]
