Modeling parity-violating spectra in Galactic dust polarization with filaments and its applications to cosmic birefringence searches

Posted by klaurent Stanford

Kavli Affiliate: Susan E. Clark | First 5 Authors: Carlos Hervías-Caimapo, Ari J. Cukierman, Patricia Diego-Palazuelos, Kevin M. Huffenberger, Susan E. Clark | Summary: We extend the dust-filament-based model presented in Herv’ias-Caimapo & Huffenberger 2022 to produce parity-violating foreground spectra by manipulating the filament orientations relative to the magnetic field. We calibrate our model to […]

Investigating the competition between the deconfinement and chiral phase transitions in light of the multimessenger observations of neutron stars

Posted by dbos Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Wen-Li Yuan, Bikai Gao, Yan Yan, Bolin Li, Renxin Xu | Summary: We extend the parity doublet model for hadronic matter and study the possible presence of quark matter inside the cores of neutron stars with the Nambu-Jona-Lasinio (NJL) model. Considering the uncertainties of the QCD phase […]

Mass determination of two Jupiter-sized planets orbiting slightly evolved stars: TOI-2420 b and TOI-2485 b

Posted by dbos MIT

Kavli Affiliate: George Ricker | First 5 Authors: Ilaria Carleo, Oscar Barrágan, Carina M. Persson, Malcolm Fridlund, Kristine W. F. Lam | Summary: Hot and warm Jupiters might have undergone the same formation and evolution path, but the two populations exhibit different distributions of orbital parameters, challenging our understanding on their actual origin. The present […]

Proof of principle X-ray reflection mass measurement of the black hole in H1743-322

Posted by dbos MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Edward Nathan, Adam Ingram, James F. Steiner, Ole König, Thomas Dauser | Summary: The black hole X-ray binary H1743-322 lies in a region of the Galaxy with high extinction, and therefore it has not been possible to make a dynamical mass measurement. In this paper we make […]

Absence of High-mass Prestellar Cores in the Orion Giant Molecular Cloud

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Wenyu Jiao, Ke Wang, Fengwei Xu, , | Summary: A fundamental difference between "core-fed" and "clump-fed" star formation theories lies in the existence or absence of high-mass cores at the prestellar stage. However, only a handful of such cores have been observed. Here, different than previous search […]
