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: Chao-Lin Kuo | First 5 Authors: M. Guzzetti, D. Zhang, C. Goodman, C. Hanretty, J. Sinnis | Summary: Axions are a well-motivated candidate for dark matter. The preeminent method to search for axion dark matter is known as the axion haloscope, which makes use of the conversion of axions to photons in a […]
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 […]
Kavli Affiliate: Ke Wang | First 5 Authors: Pengfei Zhang, Yu Gao, Xiansong Xu, Ning Wang, Hang Dong | Summary: Non-equilibrium quantum transport is crucial to technological advances ranging from nanoelectronics to thermal management. In essence, it deals with the coherent transfer of energy and (quasi-)particles through quantum channels between thermodynamic baths. A complete understanding […]
Kavli Affiliate: Jia Liu | First 5 Authors: Chengqi Dong, Zhiyuan Cao, S Kevin Zhou, Jia Liu, | Summary: Stock price prediction is of significant importance in quantitative investment. Existing approaches encounter two primary issues: First, they often overlook the crucial role of capturing short-term stock fluctuations for predicting high-volatility returns. Second, mainstream methods, relying […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: C. Bartram, C. Boutan, T. Braine, J. H. Buckley, T. J. Caligiure | Summary: From CMB polarization data alone we reconstruct the CMB lensing power spectrum, comparable in overall constraining power to previous temperature-based reconstructions, and an unlensed E-mode power spectrum. The observations, taken in 2019 and […]
Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Dheeraj Pasham, Eric Coughlin, Chris Nixon, Michal Zajacek, Petra Sukova | Summary: SwJ023017.0+283603 (SwJ0230) exhibited soft X-ray (0.3-1.0 keV) eruptions recurring roughly every 22 days. We present results from an extended monitoring campaign of SwJ0230 using Swift, NICER, and deep XMM-Newton observations. Our main findings are: 1) […]
