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 […]

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 […]

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 […]

Polarized muons and the origin of biological homochirality

Kavli Affiliate: Roger D. Blandford | First 5 Authors: Noemie Globus, Roger D. Blandford, Anatoli Fedynitch, , | Summary: While biologists have not yet reached a consensus on the definition of life, homochirality – the specific molecular handedness of biomolecules – is a phenomenon only produced by life. The unraveling of its origin requires interdisciplinary […]

DeepGhostBusters: Using Mask R-CNN to Detect and Mask Ghosting and Scattered-Light Artifacts from Optical Survey Images

Kavli Affiliate: Brian Nord | First 5 Authors: Dimitrios Tanoglidis, Aleksandra Ćiprijanović, Alex Drlica-Wagner, Brian Nord, Michael H. L. S. Wang | Summary: Wide-field astronomical surveys are often affected by the presence of undesirable reflections (often known as "ghosting artifacts" or "ghosts") and scattered-light artifacts. The identification and mitigation of these artifacts is important for […]

Subtle Data Crimes: Naively training machine learning algorithms could lead to overly-optimistic results

Kavli Affiliate: Ke Wang | First 5 Authors: Efrat Shimron, Jonathan I. Tamir, Ke Wang, Michael Lustig, | Summary: While open databases are an important resource in the Deep Learning (DL) era, they are sometimes used "off-label": data published for one task are used for training algorithms for a different one. This work aims to […]

Monte Carlo simulations of neutrino and charged lepton propagation in the Earth with nuPyProp

Kavli Affiliate: Angela Olinto | First 5 Authors: Sameer Patel, Mary Hall Reno, Yosui Akaike, Luis Anchordoqui, Douglas Bergman | Summary: An accurate modeling of neutrino flux attenuation and the distribution of leptons they produce in transit through the Earth is an essential component to determine neutrino flux sensitivities of underground, sub-orbital and space-based detectors. […]

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 […]
