Kavli Affiliate: Misao Sasaki | First 5 Authors: Kaloian D. Lozanov, Misao Sasaki, , , | Summary: We consider a scalar field theory with a Minkowski false vacuum and an unbounded (or very deep) true vacuum. We show compelling evidence that an AdS bubble of vanishing total energy, embedded in asymptotically flat spacetime, generically undergoes […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Katsuya T. Abe, Masamune Oguri, Simon Birrer, Narayan Khadka, Philip J. Marshall | Summary: Time delays in both galaxy- and cluster-scale strong gravitational lenses have recently attracted a lot of attention in the context of the Hubble tension. Future wide-field cadenced surveys, such as the LSST, […]
Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Roman Schnabel, Nergis Mavalvala, David E. McClelland, Ping Koy Lam, | Summary: Einstein’s General Theory of Relativity predicts that accelerating mass distributions produce gravitational radiation, analogous to electromagnetic radiation from accelerating charges. These gravitational waves have not been directly detected to date, but are expected to open […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: William Roster, Mara Salvato, Sven Krippendorf, Aman Saxena, Raphael Shirley | Summary: Computing photo-z for AGN is challenging, primarily due to the interplay of relative emissions associated with the SMBH and its host galaxy. SED fitting methods, effective in pencil-beam surveys, face limitations in all-sky surveys with […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Janhavi Baghel, P. Kharb, T. Hovatta, Luis C. Ho, C. Harrison | Summary: We present polarization images with the Karl G. Jansky Very Large Array (VLA) in A and B-array configurations at 6 GHz of 7 radio-loud (RL) quasars and 8 BL Lac objects belonging to […]
