HD 222237 b: a long period super-Jupiter around a nearby star revealed by radial-velocity and Hipparcos-Gaia astrometry

Kavli Affiliate: Avi Shporer | First 5 Authors: Guang-Yao Xiao, Fabo Feng, Stephen A. Shectman, C. G. Tinney, Johanna K. Teske | Summary: Giant planets on long period orbits around the nearest stars are among the easiest to directly image. Unfortunately these planets are difficult to fully constrain by indirect methods, e.g., transit and radial […]

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 AGNs: 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 $sim 10^{6-8}~M_odot$. These AGN populations are considered crucial for understanding early […]

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 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 scattering off a nucleus […]

Confirming the Tidal Tails of the Young Open Cluster Blanco 1 with TESS Rotation Periods

Kavli Affiliate: Andrew M. Vanderburg | First 5 Authors: Lizhou Sha, Andrew M. Vanderburg, Luke G. Bouma, Chelsea X. Huang, | Summary: Blanco 1 is an $approx 130,mathrm{Myr}$ open cluster located 240 pc from the Sun below the Galactic plane. Recent studies have reported the existence of diffuse tidal tails extending 50-60 pc from the […]

Low-energy critical behavior in two-dimensional tilted semi-Dirac semimetals driven by fermion-fermion interactions

Kavli Affiliate: Jing Wang | First 5 Authors: Wen Liu, Wen-Hao Bian, Xiao-Zhuo Chu, Jing Wang, | Summary: Employing the renormalization group approach, we carefully investigate the critical behavior of two-dimensional tilted semi-Dirac semimetals induced by the fermion-fermion interactions in the low-energy regime. After incorporating all one-loop corrections, we derive the coupled RG equations of […]
