Ergomagnetosphere, Ejection Disc, Magnetopause in M87. I Global Flow of Mass, Angular Momentum, Energy and Current

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Noemie Globus, , , | Summary: We interpret the 1.3mm VLBI observations made by the Event Horizon Telescope of the black hole in M87. It is proposed that, instead of being a torus of accreting gas, the ring is a rotating, magnetically-dominated ergomagnetosphere that can […]

A Mini-Neptune from TESS and CHEOPS Around the 120 Myr Old AB Dor member HIP 94235

Kavli Affiliate: George Ricker | First 5 Authors: George Zhou, Christopher P. Wirth, Chelsea X. Huang, Alexander Venner, Kyle Franson | Summary: The TESS mission has enabled discoveries of the brightest transiting planet systems around young stars. These systems are the benchmarks for testing theories of planetary evolution. We report the discovery of a mini-Neptune […]

Inferences on relations between distant supermassive black holes and their hosts complemented by the galaxy fundamental plane

Kavli Affiliate: John Silverman | First 5 Authors: John Silverman, Junyao Li, Xuheng Ding, , | Summary: The realization of fundamental relations between supermassive black holes and their host galaxies would have profound implications in astrophysics. To add further context to studies of their co-evolution, an investigation is carried out to gain insight as to […]

Testing High-Energy Emission Models for Blazars with X-ray Polarimetry

Kavli Affiliate: Roger W. Romani | First 5 Authors: Abel L. Peirson, Ioannis Liodakis, Roger W. Romani, , | Summary: Both leptonic and hadronic emission processes may contribute to blazar jet emission; which dominates in blazars’s high energy emission component remains an open question. Some intermediate synchrotron peaked blazars transition from their low to high […]

Bayesian Data Analysis for Sky-averaged 21-cm Experiments in the Presence of Ionospheric Effects

Kavli Affiliate: George Efstathiou | First 5 Authors: Emma Shen, Dominic Anstey, Eloy de Lera Acedo, Anastasia Fialkov, | Summary: The ionosphere introduces chromatic distortions on low frequency radio waves, and thus poses a hurdle for 21-cm cosmology. In this paper we introduce time-varying chromatic ionospheric effects on simulated antenna temperature data of a global […]

Parametric Level-sets Enhanced To Improve Reconstruction (PaLEnTIR)

Kavli Affiliate: Eric Miller | First 5 Authors: Ege Ozsar, Misha Kilmer, Eric Miller, Eric de Sturler, Arvind Saibaba | Summary: In this paper, we consider the restoration and reconstruction of piecewise constant objects in two and three dimensions using PaLEnTIR, a significantly enhanced Parametric level set (PaLS) model relative to the current state-of-the-art. The […]
