Inferring host galaxy properties of LIGO-Virgo-KAGRA’s black holes

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Aditya Vijaykumar, Maya Fishbach, Susmita Adhikari, Daniel E. Holz, | Summary: Observations of gravitational waves from binary black hole (BBH) mergers have measured the redshift evolution of the BBH merger rate. The number density of galaxies in the Universe evolves differently with redshift based on their […]

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 […]
