Kavli Affiliate: Stuart Marshall | 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: Aaron Roodman | 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 (BFE). This particularly impacts bright calibration stars, which appear larger than their intrinsic shape, creating a […]
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 | 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 initial limits on a model-independent non-relativistic effective field theory describing the complete set of possible interactions of a […]
Kavli Affiliate: D. B. Macfarlane | Summary:Using the entire BaBar $Υ(4S)$ data set, the first two-dimensional unbinned angular analysis of the semileptonic decay $overlineB rightarrow D ell^- overlineν_ell$ is performed, employing hadronic reconstruction of the tag-side $B$ meson from $Υ(4S)to BoverlineB$. Here, $ell$ denotes the light charged leptons $e$ and $μ$. A novel data-driven signal-background […]
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: Sarah Church | 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 16-pixel spectroscopic focal plane array Argus on the 100-m Robert C. Byrd Green Bank Telescope (GBT) […]
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: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, , , | Summary: We place limits on dark matter made up of compact objects significantly heavier than a solar mass, such as MACHOs or primordial black holes (PBHs). In galaxies, the gas of such objects is generally hotter than the […]
