Modeling Nearest Neighbor distributions of biased tracers using Hybrid Effective Field Theory

Kavli Affiliate: Tom Abel | First 5 Authors: Arka Banerjee, Nickolas Kokron, Tom Abel, , | Summary: We investigate the application of Hybrid Effective Field Theory (HEFT) — which combines a Lagrangian bias expansion with subsequent particle dynamics from $N$-body simulations — to the modeling of $k$-Nearest Neighbor Cumulative Distribution Functions ($k{rm NN}$-${rm CDF}$s) of […]

UV Fluorescence Traces Gas and LyA Evolution in Protoplanetary Disks

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Nicole Arulanantham, Kevin France, Keri Hoadley, P. C. Schneider, Catherine C. Espaillat | Summary: Ultraviolet spectra of protoplanetary disks trace distributions of warm gas at radii where rocky planets form. We combine HST-COS observations of H2 and CO emission from 12 classical T Tauri stars to […]

Analysis of Polarimetry Data with Angular Uncertainties

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Herman L. Marshall, , , , | Summary: For a track based polarimeter, such as the Imaging X-ray Polarimetry Explorer (IXPE), the sensitivity to polarization depends on the modulation factor, which is a strong function of energy. In previous work, a likelihood method was developed that […]

Hints of spin-orbit resonances in the binary black hole population

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Vijay Varma, Sylvia Biscoveanu, Maximiliano Isi, Will M. Farr, Salvatore Vitale | Summary: Binary black hole spin measurements from gravitational wave observations can reveal the binary’s evolutionary history. In particular, the spin orientations of the component black holes within the orbital plane, $phi_1$ and $phi_2$, can be […]

Measuring binary black hole orbital-plane spin orientations

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Vijay Varma, Maximiliano Isi, Sylvia Biscoveanu, Will M. Farr, Salvatore Vitale | Summary: Binary black hole spins are among the key observables for gravitational wave astronomy. Among the spin parameters, their orientations within the orbital plane, $phi_1$, $phi_2$ and $Delta phi=phi_1-phi_2$, are critical for understanding the prevalence […]

The Simplest and Most Predictive Model of Muon $g-2$ and Thermal Dark Matter

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Ian Holst, Dan Hooper, Gordan Krnjaic, , | Summary: The long-standing $4.2 , sigma$ muon $g-2$ anomaly may be the result of a new particle species which could also couple to dark matter and mediate its annihilations in the early universe. In models where both muons and […]

The Effect of Mission Duration on LISA Science Objectives

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Manuel Arca Sedda, Stanislav Babak, Christopher P. L. Berry, Emanuele Berti | Summary: The science objectives of the LISA mission have been defined under the implicit assumption of a 4 yr continuous data stream. Based on the performance of LISA Pathfinder, it is […]

Extragalactic magnetism with SOFIA (Legacy Program) — II: A magnetically-driven flow in the starburst ring of NGC 1097

Kavli Affiliate: Susan E. Clark | First 5 Authors: Enrique Lopez-Rodriguez, Rainer Beck, Susan E. Clark, Annie Hughes, Alejandro S. Borlaff | Summary: Galactic bars are frequent in disk galaxies and they may support the transfer of matter towards the central engine of active nuclei. The barred galaxy NGC 1097 has magnetic forces controlling the […]

Sub-second periodicity in a fast radio burst

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, Bridget C. Andersen, Kevin Bandura, Mohit Bhardwaj, P. J. Boyle | Summary: The origin of fast radio bursts (FRBs), millisecond-duration flashes of radio waves that are visible at distances of billions of light-years, remains an open astrophysical question. Here we report the detection […]

XMM-Newton Observes the Intrabinary Shock of PSR J1959+2048

Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, Hongjun An, , | Summary: In a multi-orbit (100 ks) $mathrm{it XMM-Newton}$ exposure of the original black widow pulsar, PSR J1959+2048, we measure the strong orbital modulation caused by intrabinary shock (IBS) emission. The IBS light curve peak appears asymmetric, which […]
