Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Yukinobu Toda, , , | Summary: The Gopakumar-Vafa type invariants on Calabi-Yau 4-folds (which are non-trivial only for genus zero and one) are defined by Klemm-Pandharipande from Gromov-Witten theory, and their integrality is conjectured. In a previous work of Cao-Maulik-Toda, $mathrm{DT}_4$ invariants with primary insertions […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Noah Kurinsky, Daniel Baxter, Yonatan Kahn, Gordan Krnjaic, Peter Abbamonte | Summary: We respond to Robinson and Michaud’s (RM) comment (arXiv:2002.08893) on our recent preprint arXiv:2002.06937, in which we discuss recent excesses in low-threshold dark matter searches, and offer a potential unifying dark matter interpretation. We thank […]
Kavli Affiliate: David Spergel | First 5 Authors: Neelima Sehgal, Simone Aiola, Yashar Akrami, Kaustuv moni Basu, Michael Boylan-Kolchin | Summary: CMB-HD is a proposed ultra-deep (0.5 uk-arcmin), high-resolution (15 arcseconds) millimeter-wave survey over half the sky that would answer many outstanding questions in both fundamental physics of the Universe and astrophysics. This survey would […]
Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Jo Dunkley, Carlos Frenk, Ofer Lahav, Alice Shapley | Summary: Cosmology now has a standard model – a remarkably simple description of the universe, its contents and its history. A symposium held last September in Cambridge, UK, gave this model a ‘health check’ and discussed […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, , , | Summary: We present a model for atmospheric wind circulation in binary millisecond pulsar (MSP) companions, showing how the optical light curve (LC) and radial velocities (RV) are sensitive to the wind flow, causing LC orbital phase shifts and […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Chang-Tse Hsieh, Yu Nakayama, Yuji Tachikawa, , | Summary: We show that there is a fermionic minimal model, i.e. a 1+1d conformal field theory which contains operators of half-integral spins in its spectrum, for each $c=1-6/m(m+1)$, $mge 3$. This generalizes the Majorana fermion for $c=1/2$, $m=3$ and […]
Kavli Affiliate: Eli Rykoff | First 5 Authors: DES Collaboration, Tim Abbott, Michel Aguena, Alex Alarcon, Sahar Allam | Summary: We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear and source photometric redshifts […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Christoph Engler, Annalisa Pillepich, Gandhali D. Joshi, Dylan Nelson, Anna Pasquali | Summary: We study the stellar-to-halo mass relation (SHMR) for central and satellite galaxies with total dynamical masses above 10^10.5 Msun using the suite of cosmological magneto-hydrodynamical simulations IllustrisTNG. In particular, we quantify environmental effects on […]
Kavli Affiliate: Roger D. Blandford | First 5 Authors: Noemie Globus, Roger D. Blandford, , , | Summary: Biological molecules chose one of two structurally, chiral systems which are related by reflection in a mirror. It is proposed that this choice was made, causally, by magnetically polarized and physically chiral cosmic-rays, which are known to […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Hao Chen, Rupak Mahapatra, Glenn Agnolet, Michael Nippe, Minjie Lu | Summary: The detection of a single quantum of energy with high efficiency and low false positive rate is of considerable scientific interest, from serving as single quantum sensors of optical and infra-red photons to enabling the […]
