Kavli Affiliate: Bruce Macintosh | First 5 Authors: Simon Petrus, Niall Whiteford, Polychronis Patapis, Beth A. Biller, Andrew Skemer | Summary: The unprecedented medium-resolution (R=1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (120-160Myr) low-mass (12-20MJup) L-T transition (L7) companion VHS1256b has opened new avenues for the in-depth characterization of substellar object […]

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Simon Petrus, Niall Whiteford, Polychronis Patapis, Beth A. Biller, Andrew Skemer | Summary: The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) companion VHS1256b gives access to a catalogue of molecular absorptions. In this study, […]

Kavli Affiliate: Aaron Roodman | First 5 Authors: Alex Broughton, Yousuke Utsumi, Andrés Plazas Malagón, Christopher Waters, Craig Lage | Summary: Thick, fully depleted charge-coupled devices (CCDs) are known to exhibit non-linear behavior at high signal levels due to the dynamic behavior of charges collecting in the potential wells of pixels, called the brighter-fatter effect […]

Kavli Affiliate: Steven W. Allen | First 5 Authors: Brandon Sandoval, Adi Foord, Steven W. Allen, Marta Volonteri, Aaron Stemo | Summary: We present an analysis searching for dual AGN among 62 high-redshift ($2.5 < z < 3.5$) X-ray sources selected from publicly available deep Chandra fields. We aim to quantify the frequency of dual […]

Kavli Affiliate: C. M. Ignarra | First 5 Authors: LZ Collaboration, J. Aalbers, D. S. Akerib, A. K. Al Musalhi, F. Alder | Summary: Following the first science results of the LUX-ZEPLIN (LZ) experiment, a dual-phase xenon time projection chamber operating from the Sanford Underground Research Facility in Lead, South Dakota, USA, we report the […]

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 […]
