Improving the Cosmological Constraints by Inferring the Formation Channel of Extreme-mass-ratio Inspirals

Posted by dbos Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Liang-Gui Zhu, Hui-Min Fan, Xian Chen, Yi-Ming Hu, Jian-dong Zhang | Summary: Extreme-mass-ratio inspirals (EMRIs) could be detected by space-borne gravitational-wave (GW) detectors, such as the Laser Interferometer Space Antenna (LISA), TianQin and Taiji. Localizing EMRIs by GW detectors can help us select candidate host galaxies, which […]

Relative alignment between gas structures and magnetic field in Orion A at different scales using different molecular gas tracers

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Wenyu Jiao, Ke Wang, Fengwei Xu, Chao Wang, Henrik Beuther | Summary: Context: Magnetic fields can play crucial roles in high-mass star formation. Nonetheless, the significance of magnetic fields at various scales and their relationship with gas structures is largely overlooked. Aims: Our goal is to examine […]

Galaxies lensing quadruply imaged quasars lie close to the centers of their lensing potentials

Posted by dbos MIT

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | Summary: In modeling the potentials of quadruply lensed quasars, investigators often employ models for the stellar surface brightness profile of the lensing galaxy for the sole purpose of eliminating its contamination of the light from the quasar images […]

Witt’s hyperbola is both predicted and observed to pass close to the lensing galaxies in quadruple quasars

Posted by dbos MIT

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Paul L. Schechter, Richard Luhtaru, , , | Summary: When a rectangular hyperbola is constructed from the image positions of a quadruply lensed quasar, as proposed by Witt (1996), it passes very close to the the lensing galaxy. The median measured perpendicular offset between the observed […]
