The Stellar Initial Mass Function and Population Properties of M89 from Optical and NIR Spectroscopy: Addressing Biases in Spectral Index Analysis

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Ilaria Lonoce, Anja Feldmeier-Krause, Wendy L. Freedman, , | Summary: The complexity of constraining the stellar initial mass function (IMF) in early-type galaxies cannot be overstated, given the necessity of both very high signal-to-noise (S/N) data and the difficulty of breaking the strong degeneracies that occur […]

Lattice Renormalization of Quantum Simulations

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Henry Lamm, Ying-Ying Li, Wanqiang Liu, | Summary: With advances in quantum computing, new opportunities arise to tackle challenging calculations in quantum field theory. We show that trotterized time-evolution operators can be related by analytic continuation to the Euclidean transfer matrix on an anisotropic lattice. […]

Measurements of the Hubble Constant: Tensions in Perspective

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, , , , | Summary: Measurement of the distances to nearby galaxies have improved rapidly in recent decades. The ever-present challenge is to reduce systematic effects, especially as greater distances are probed, and the uncertainties become larger. In this paper, we combine several […]

Expediting DECam Multimessenger Counterpart Searches with Convolutional Neural Networks

Kavli Affiliate: Brian Nord | First 5 Authors: Adam Shandonay, Robert Morgan, Keith Bechtol, Clecio R. Bom, Brian Nord | Summary: Searches for counterparts to multimessenger events with optical imagers use difference imaging to detect new transient sources. However, even with existing artifact detection algorithms, this process simultaneously returns several classes of false positives: false […]

GRUMPY: a simple framework for realistic forward-modelling of dwarf galaxies

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, Viraj Manwadkar, , , | Summary: We present a simple regulator-type framework designed specifically for modelling formation of dwarf galaxies. We explore sensitivity of model predictions for the stellar mass–halo mass and stellar mass–metallicity relations to different modelling choices and parameter values. Despite its simplicity, […]

SENSEI: Characterization of Single-Electron Events Using a Skipper-CCD

Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Ana Botti, Mariano Cababie, Gustavo Cancelo | Summary: We use a science-grade Skipper Charge Coupled Device (Skipper-CCD) operating in a low-radiation background environment to develop a semi-empirical model that characterizes the origin of single-electron events in CCDs. We identify, separate, and quantify […]
