Kavli Affiliate: Bruce Macintosh | First 5 Authors: Andrew D. Thomas, Eric L. Nielsen, Robert J. De Rosa, Anne E. Peck, Bruce Macintosh | Summary: We present new spatially resolved astrometry and photometry of the CD-27 11535 system, a member of the $beta$ Pictoris moving group consisting of two resolved K-type stars on a $sim$20-year […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: BaBar Collaboration, J. P. Lees, V. Poireau, V. Tisserand, E. Grauges | Summary: Using the entire BaBar $Upsilon(4S)$ data set, the first two-dimensional unbinned angular analysis of the semileptonic decay $overline{B} rightarrow D ell^- overline{nu}_ell$ is performed, employing hadronic reconstruction of the tag-side $B$ meson from […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Joseph Thornton, Alexandra Amon, Risa H. Wechsler, Susmita Adhikari, Yao-Yuan Mao | Summary: We present a novel approach to extracting dwarf galaxies from photometric data to measure their average halo mass profile with weak lensing. We characterise their stellar mass and redshift distributions with a spectroscopic […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Katie A. Crotts, Brenda C. Matthews, Gaspard Duchêne, Thomas M. Esposito, Ruobing Dong | Summary: The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey (GPIES) imaged twenty-four debris disks in polarized $H$-band light, while other programs observed half […]
Kavli Affiliate: Sarah Church | First 5 Authors: Jialu Li, Andrew I Harris, Erik Rosolowsky, Amanda Kepley, David Frayer | Summary: We report observations of the ground state transitions of $^{12}$CO, $^{13}$CO C$^{18}$O, HCN, and HCO$^+$ at 88-115 GHz in the inner region of the nearby galaxy IC 342. These data were obtained with the […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Kuan Liu, Fei Xie, Yi-Han Liu, Chi-Yung Ng, Niccolo’ Bucciantini | Summary: In this paper, we present a full spatially resolved polarization map for the Vela Pulsar Wind Nebula (PWN) observed by IXPE. By employing effective background discrimination techniques, our results show a remarkably high degree […]
Kavli Affiliate: Sven Herrmann | First 5 Authors: Jan Scheumann, Dennis Philipp, Sven Herrmann, Eva Hackmann, Benny Rievers | Summary: All experiments to date are in remarkable agreement with the predictions of Einstein’s theory of gravity, General Relativity. Besides the classical tests, involving light deflection, orbit precession, signal delay, and the gravitational redshift, modern technology […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Aaron C. Trigg, Eric Burns, Oliver J. Roberts, Michela Negro, Dmitry S. Svinkin | Summary: Magnetars are slowly rotating neutron stars that possess the strongest magnetic fields ($10^{14}-10^{15} mathrm{G}$) known in the cosmos. They display a range of transient high-energy electromagnetic activity. The brightest and most energetic […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Anirban Das, Noah Kurinsky, Rebecca K. Leane, , | Summary: In the past few years, many mesoscale systems have been proposed as possible detectors of sub-GeV dark matter particles. In this work, we point out the feasibility of probing dark matter-nucleon scattering cross section using superconductor-based quantum […]
Kavli Affiliate: Peter Graham | First 5 Authors: Thomas G. White, Hannah Poole, Emma E. McBride, Matthew Oliver, Adrien Descamps | Summary: We present the first direct observations of acoustic waves in warm dense matter. We analyze wavenumber- and energy-resolved X-ray spectra taken from warm dense methane created by laser-heating a cryogenic liquid jet. X-ray […]
