Mitigation of the Brighter-Fatter Effect in the LSST Camera

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 […]

Generating Interpretable Networks using Hypernetworks

Kavli Affiliate: Max Tegmark | First 5 Authors: Isaac Liao, Ziming Liu, Max Tegmark, , | Summary: An essential goal in mechanistic interpretability to decode a network, i.e., to convert a neural network’s raw weights to an interpretable algorithm. Given the difficulty of the decoding problem, progress has been made to understand the easier encoding […]

Prospects for constraining quasar ages with fiber spectrographs: Quasar-induced Ly$α$ emission from the intergalactic medium

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryuichiro Hada, Masahiro Takada, Akio K. Inoue, , | Summary: We present a theoretical framework for linking quasar properties, such as quasar age, to the surrounding Ly$alpha$ emission intensity. In particular, we focus on a method for mapping the large-scale structure of Ly$alpha$ emission intensity with galaxy […]

Resolving Clumpy vs. Extended Ly-$α$ In Strongly Lensed, High-Redshift Ly-$α$ Emitters

Kavli Affiliate: Michael Gladders | First 5 Authors: Alexander Navarre, Gourav Khullar, Matthew Bayliss, Håkon Dahle, Michael Florian | Summary: We present six strongly gravitationally lensed Ly-$alpha$ Emitters (LAEs) at $zsim4-5$ with HST narrowband imaging isolating Ly-$alpha$. Through complex radiative transfer Ly-$alpha$ encodes information about the spatial distribution and kinematics of the neutral hydrogen upon […]

Searching for the Highest-z Dual AGN in the Deepest Chandra Surveys

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 […]
