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 […]

Probing ultrafast magnetization dynamics via synthetic axion fields

Posted by dbos MIT

Kavli Affiliate: Frank Wilczek | First 5 Authors: Leon Shaposhnikov, Eduardo Barredo-Alamilla, Frank Wilczek, Maxim A. Gorlach, | Summary: Spatial structuring of materials at subwavelength scales underlies the concept of metamaterials possessing exotic properties beyond those of the constituent media. Temporal modulation of material parameters enables further functionalities. Here, we show that high-frequency oscillations of […]

Predicting Many Properties of Crystals by a Single Deep Learning Model

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Haosheng Xu, Dongheng Qian, Jing Wang, , | Summary: The use of machine learning methods for predicting the properties of crystalline materials encounters significant challenges, primarily related to input encoding, output versatility, and interpretability. Here, we introduce CrystalBERT, an adaptable transformer-based framework with novel structure that integrates […]

Measurement of the energy dependence of the $e^+e^- to Bbar{B}$, $Bbar{B}{}^*$, and $B^*bar{B}{}^*$ cross sections at Belle~II

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We report measurements of the $e^+e^- to Bbar{B}$, $Bbar{B}{}^*$, and $B^*bar{B}{}^*$ cross sections at four energies, 10653, 10701, 10746 and 10805 MeV, using data collected by the Belle~II experiment. We reconstruct one $B$ meson […]

Photometric detection at $7.7 μmathrm{m}$ of a galaxy beyond redshift $14$ with JWST/MIRI

Posted by dbos Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Jakob M. Helton, George H. Rieke, Stacey Alberts, Zihao Wu, Daniel J. Eisenstein | Summary: The James Webb Space Telescope (JWST) has spectroscopically confirmed numerous galaxies at $z > 10$. While weak rest-ultraviolet emission lines have only been seen in a handful of sources, the stronger rest-optical […]
