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 […]

An Information-state based Approach to the Optimal Output Feedback Control of Nonlinear Systems

Kavli Affiliate: Ran Wang | First 5 Authors: , , , , | Summary: This paper develops a data-based approach to the closed-loop output feedback control of nonlinear dynamical systems with a partial nonlinear observation model. We propose an information state based approach to rigorously transform the partially observed problem into a fully observed problem […]

Long-Range Superconducting Proximity Effect in Nickel Nanowires

Kavli Affiliate: Ke Wang | First 5 Authors: Jue Jiang, Weiwei Zhao, Fei Wang, Renzhong Du, Ludi Miao | Summary: When a ferromagnet is placed in contact with a superconductor, owing to incompatible spin order, the Cooper pairs from the superconductor cannot survive more than one or two nanometers inside the ferromagnet. This is confirmed […]

Warming up cold inflation

Kavli Affiliate: Peter W. Graham | First 5 Authors: William DeRocco, Peter W. Graham, Saarik Kalia, , | Summary: The axion is a well-motivated candidate for the inflaton, as the radiative corrections that spoil many single-field models are avoided by virtue of its shift symmetry. However, axions generically couple to gauge sectors. As the axion […]

Modelling correlated variability in accreting black holes: the effect of high density and variable ionisation on reverberation lags

Kavli Affiliate: Erin Kara | First 5 Authors: Guglielmo Mastroserio, Adam Ingram, Jingyi Wang, Javier A. GarcĂ­a, Michiel van der Klis | Summary: We present a new release of the RELTRANS model to fit the complex cross-spectrum of accreting black holes as a function of energy. The model accounts for continuum lags and reverberation lags […]

The Subaru HSC weak lensing mass-observable scaling relations of spectroscopic galaxy groups from the GAMA survey

Kavli Affiliate: Masahiro Takada | First 5 Authors: Divya Rana, Surhud More, Hironao Miyatake, Takahiro Nishimichi, Masahiro Takada | Summary: We utilize the galaxy shape catalogue from the first-year data release of the Subaru Hyper Suprime-cam Survey (HSC) to study the dark matter content of galaxy groups in the Universe using weak lensing. We use […]

21cmVAE: A VAE-based Emulator of the 21-cm Global Signal

Kavli Affiliate: George Efstathiou | First 5 Authors: Christian Hellum Bye, Stephen K. N. Portillo, Anastasia Fialkov, , | Summary: Considerable observational efforts are being dedicated to measuring the sky-averaged (global) 21-cm signal of neutral hydrogen from Cosmic Dawn and the Epoch of Reionization. Deriving observational constraints on the astrophysics of this era requires modelling […]
