Kavli Affiliate: Masahito Yamazaki | First 5 Authors: So Chigusa, Masahito Yamazaki, , , | Summary: We consider dark sector scenarios where dark matter is accompanied by a dark photon and multiple-flavor dark fermions charged under the dark gauge group. We study quantum interference effects in dark sector jets, where multiple dark photons are emitted […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Roland M. Crocker, Oscar Macias, Dougal Mackey, Mark R. Krumholz, Shin’ichiro Ando | Summary: The Fermi Bubbles are giant, gamma-ray emitting lobes emanating from the nucleus of the Milky Way discovered in 1-100 GeV data collected by the Large Area Telescope on board the Fermi Gamma-Ray Space […]

Krumholz, Shin’ichiro Ando | Summary: The Fermi Bubbles are giant, gamma-ray emitting lobes emanating from the nucleus of the Milky Way discovered in ~1-100 GeV data collected by the Large Area Telescope on board the Fermi Gamma-Ray Space […]
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 […]
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 observed annular ring is a rotating, magnetically-dominated ergomagnetosphere […]
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 […]
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 […]
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 […]
Kavli Affiliate: Peter Graham | First 5 Authors: Jim Alexander, Vassilis Anastassopoulos, Rick Baartman, Stefan Baeßler, Franco Bedeschi | Summary: We describe a proposal to search for an intrinsic electric dipole moment (EDM) of the proton with a sensitivity of targetsens, based on the vertical rotation of the polarization of a stored proton beam. The […]
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 […]
