Constraining Inflation with the BICEP/Keck CMB Polarization Experiments

Posted by Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The BICEP/Keck Collaboration, :, P. A. R. Ade, Z. Ahmed, M. Amiri | Summary: The BICEP/$textit{Keck}$ (BK) series of cosmic microwave background (CMB) polarization experiments has, over the past decade and a half, produced a series of field-leading constraints on cosmic inflation via measurements of the "B-mode" […]

Net-zero gas inflow: deconstructing the gas consumption history of a massive quiescent galaxy with JWST and ALMA

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jan Scholtz, Francesco D’Eugenio, Roberto Maiolino, Pablo G. Pérez-González, Chiara Circosta | Summary: JWST is discovering increasing numbers of quiescent galaxies 1–2 billion years after the Big Bang, whose redshift, high mass, and old stellar ages indicate that their formation and quenching were surprisingly rapid. This fast-paced […]

Gravitational Production of Completely Dark Photons with Nonminimal Couplings to Gravity

Posted by dbos Chicago

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: Dark photons are a theorized massive spin-1 particle which can be produced via various mechanisms, including cosmological gravitational particle production (GPP) in the early universe. In this work, we extend previous results for GPP of […]

X-ray and Radio campaign of the Z-source GX 340+0: discovery of X-ray polarization and its implications

Posted by dbos MIT

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Yash Bhargava, Mason Ng, Liang Zhang, Arvind Balasubramanian, Thomas D. Russell | Summary: We present the discovery of X-ray polarization from the neutron star low-mass X-ray binary and Z-source, GX~340$+$0, using an Imaging X-ray Polarimetry Explorer (IXPE) observation in March 2024. Along with the IXPE observation, we […]
