An IXPE-Led X-ray Spectro-Polarimetric Campaign on the Soft State of Cygnus X-1: X-ray Polarimetric Evidence for Strong Gravitational Lensing

Posted by dbos MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: James F. Steiner, Edward Nathan, Kun Hu, Henric Krawczynski, Michal Dovciak | Summary: We present the first X-ray spectropolarimetric results for Cygnus X-1 in its soft state from a campaign of five IXPE observations conducted during 2023 May-June. Companion multiwavelength data during the campaign are likewise […]

JADES: Physical properties of Ly$α$ and non-Ly$α$ emitters at z ~ 4.8-9.6

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Nimisha Kumari, Renske Smit, Joris Witstok, Marco Sirianni, Roberto Maiolino | Summary: We investigate the physical properties of Lyman-alpha emitters (LAEs) and non-Lyman-alpha emitters (non-LAEs) at z$sim$4.8–9.6 via a stacking analysis of 253 JWST/NIRSpec spectra of galaxies observed as part of the JWST Advanced Deep Extragalactic Survey […]

Weak-lensing Shear-selected Galaxy Clusters from the Hyper Suprime-Cam Subaru Strategic Program: II. Cosmological Constraints from the Cluster Abundance

Posted by dbos Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: I-Non Chiu, Kai-Feng Chen, Masamune Oguri, Markus M. Rau, Hironao Miyatake | Summary: We present cosmological constraints using the abundance of weak-lensing shear-selected galaxy clusters in the Hyper Suprime-Cam (HSC) Subaru Strategic Program. The clusters are selected on the mass maps constructed using the three-year (Y3) weak-lensing […]

[OIII] emission in z=2 quasars with and without Broad Absorption Lines

Posted by dbos Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Matthew J. Temple, Amy L. Rankine, Manda Banerji, Joseph F. Hennawi, Paul C. Hewett | Summary: Understanding the links between different phases of outflows from active galactic nuclei is a key goal in extragalactic astrophysics. Here we compare [OIII] $lambdalambda$4960,5008 outflow signatures in quasars with and without […]

Reducing Model Error Using Optimised Galaxy Selection: Weak Lensing Cluster Mass Estimation

Posted by dbos Chicago

Kavli Affiliate: Lindsey Bleem | First 5 Authors: Markus Michael Rau, Florian Kéruzoré, Nesar Ramachandra, Lindsey Bleem, | Summary: Galaxy clusters are one of the most powerful probes to study extensions of General Relativity and the Standard Cosmological Model. Upcoming surveys like the Vera Rubin Observatory’s Legacy Survey of Space and Time are expected to […]

Disk Assembly of the Milky Way Suggested from the Time-resolved Chemical Abundance

Posted by dbos Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Enci Wang, Jianhui Lian, Yingjie Peng, Xin Wang, | Summary: Both simulations and observations suggest that the disk assembly of galaxies is governed by the interplay between coplanar gas inflow, ex-planar gas outflow and in-situ star formation on the disk, known as the leaky accretion disk. This […]
