Hyper Suprime-Cam Subaru Strategic Program: A Mass-Dependent Slope of the Galaxy Size-Mass Relation at $z<1$

Kavli Affiliate: John D. Silverman | First 5 Authors: Lalitwadee Kawinwanichakij, John D. Silverman, Xuheng Ding, Angelo George, Ivana Damjanov | Summary: We present the galaxy size-mass ($R_{e}-M_{ast}$) distributions using a stellar-mass complete sample of $sim1.5$ million galaxies, covering $sim100$ deg$^2$, with $log(M_{ast}/M_{odot})>10.2~(9.2)$ over the redshift range $0.2<z<1.0$ $(z<0.6)$ from the second public data release […]

Dark matter constraint with gamma-ray galaxies cross correlation scales with N

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, Oscar Macias, | Summary: A new method to constrain the dark matter annihilation cross section by taking the cross correlation of gamma-ray diffuse maps and galaxies is proposed. As a result, the statistical power of constraining the annihilation cross section […]

Dark matter constraints with stacked gamma rays scales with the number of galaxies

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, Oscar Macias, | Summary: Low-surface-brightness galaxies (LSBGs) are interesting targets for searches of dark matter emission due to their low baryonic content. However, predicting their expected dark matter emissivities is difficult because of observational challenges in their distance measurements. Here […]

Search for $Z^{‘} rightarrow μ^{+} μ^{-}$ in the $L_μ{-} L_τ$ gauge-symmetric model at Belle

Kavli Affiliate: T. Higuchi | First 5 Authors: T. Czank, I. Jaegle, A. Ishikawa, I. Adachi, K. Adamczyk | Summary: We search for a new gauge boson $Z’$ that couples only to heavy leptons and their corresponding neutrinos in the process $e^{+} e^{-} rightarrow Z'(rightarrow mu^{+}mu^{-}) mu^{+}mu^{-}$, using a 643 fb$^{-1}$ data sample collected by […]

CompilerGym: Robust, Performant Compiler Optimization Environments for AI Research

Kavli Affiliate: Jia Liu | First 5 Authors: Chris Cummins, Bram Wasti, Jiadong Guo, Brandon Cui, Jason Ansel | Summary: Interest in applying Artificial Intelligence (AI) techniques to compiler optimizations is increasing rapidly, but compiler research has a high entry barrier. Unlike in other domains, compiler and AI researchers do not have access to the […]

SNEWPY: A Data Pipeline from Supernova Simulations to Neutrino Signals

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Amanda L. Baxter, Segev BenZvi, Joahan Castaneda Jaimes, Alexis Coleiro, Marta Colomer Molla | Summary: Current neutrino detectors will observe hundreds to thousands of neutrinos from a Galactic supernovae, and future detectors will increase this yield by an order of magnitude or more. With such a data […]

Dark matter transient annihilations in the early Universe

Kavli Affiliate: Jia Liu | First 5 Authors: Katsuya Hashino, Jia Liu, Xiao-Ping Wang, Ke-Pan Xie, | Summary: The cosmological evolution can modify the dark matter (DM) properties in the early Universe to be vastly different from the properties today. Therefore, the relation between the relic abundance and the DM constraints today needs to be […]

Categorical wall-crossing formula for Donaldson-Thomas theory on the resolved conifold

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: We prove wall-crossing formula for categorical Donaldson-Thomas invariants on the resolved conifold, which categorifies Nagao-Nakajima wall-crossing formula for numerical DT invariants on it. The categorified Hall products are used to describe the wall-crossing formula as semiorthogonal decompositions. A successive application […]

The stellar mass versus stellar metallicity relation of star-forming galaxies at $1.6le zle3.0$ and implications for the evolution of the $α$-enhancement

Kavli Affiliate: John D. Silverman | First 5 Authors: Daichi Kashino, Simon J. Lilly, Alvio Renzini, Emanuele Daddi, Giovanni Zamorani | Summary: We measure the relationship between stellar mass and stellar metallicity, the stellar mass–metallicity relation (MZR), for 1336 star-forming galaxies at $1.6le zle3.0$ (<z>=2.2) using rest-frame far-ultraviolet spectra from the zCOSMOS-deep survey. High signal-to-noise […]
