Observational Evidence to Support a Dense Ambient Medium Shaping the Jet in 3C 84
Jongho Park, Motoki Kino, Hiroshi Nagai +4
Highly collimated relativistic jets are a defining feature of certain active galactic nuclei (AGN), yet their formation mechanism remains elusive. Previous observations and theoret…
An extremely energetic cosmic ray observed by a surface detector array
Telescope Array Collaboration
Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest energy events thought to come from extragalactic sources. Their arrival is infrequent, s…
First M87 Event Horizon Telescope Results. IX. Detection of Near-horizon Circular Polarization
The Event Horizon Telescope Collaboration
Event Horizon Telescope (EHT) observations have revealed a bright ring of emission around the supermassive black hole at the center of the M87 galaxy. EHT images in linear polariza…
Polarimetric Geometric Modeling for mm-VLBI Observations of Black Holes
Freek Roelofs, Michael D. Johnson, Andrew Chael +4
The Event Horizon Telescope (EHT) is a millimeter very long baseline interferometry (VLBI) array that has imaged the apparent shadows of the supermassive black holes M87* and Sagit…
First Sagittarius A* Event Horizon Telescope Results. VI: Testing the Black Hole Metric
The Event Horizon Telescope Collaboration
Astrophysical black holes are expected to be described by the Kerr metric. This is the only stationary, vacuum, axisymmetric metric, without electromagnetic charge, that satisfies…
First Sagittarius A* Event Horizon Telescope Results. III: Imaging of the Galactic Center Supermassive Black Hole
The Event Horizon Telescope Collaboration
We present the first event-horizon-scale images and spatiotemporal analysis of Sgr A* taken with the Event Horizon Telescope in 2017 April at a wavelength of 1.3 mm. Imaging of Sgr…
First Sagittarius A* Event Horizon Telescope Results. V. Testing Astrophysical Models of the Galactic Center Black Hole
The Event Horizon Telescope Collaboration
In this paper, we provide a first physical interpretation for the Event Horizon Telescope (EHT)'s 2017 observations of Sgr A*. Our main approach is to compare resolved EHT data at…
First Sagittarius A* Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole in the Center of the Milky Way
The Event Horizon Telescope Collaboration
We present the first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A), the Galactic center source associated with a supermassive black hole. These observati…
First Sagittarius A* Event Horizon Telescope Results. IV. Variability, Morphology, and Black Hole Mass
The Event Horizon Telescope Collaboration
In this paper we quantify the temporal variability and image morphology of the horizon-scale emission from Sgr A*, as observed by the EHT in 2017 April at a wavelength of 1.3 mm. W…
First Sagittarius A* Event Horizon Telescope Results. II. EHT and Multi-wavelength Observations, Data Processing, and Calibration
The Event Horizon Telescope Collaboration
We present Event Horizon Telescope (EHT) 1.3 mm measurements of the radio source located at the position of the supermassive black hole Sagittarius A* (Sgr A*), collected during th…
Effects of Annihilation with Low-Energy Neutrinos on High-Energy Neutrinos from Binary Neutron Star Mergers and Rare Core-Collapse Supernovae
Gang Guo, Yong-Zhong Qian, Meng-Ru Wu
We explore the possibility that high-energy (HE) neutrinos produced from choked jets can be annihilated with low-energy (LE) neutrinos emitted from the accretion disk around a blac…
Energy distribution and substructure formation in astrophysical MHD simulations
Fatemeh Kayanikhoo, Miljenko Cemeljic, Maciek Wielgus +1
During substructure formation in magnetized astrophysical plasma, dissipation of magnetic energy facilitated by magnetic reconnection affects the system dynamics by heating and acc…
Neutrinos and nucleosynthesis of elements
Tobias Fischer, Gang Guo, Karlheinz Langanke +3
Neutrinos are known to play important roles in many astrophysical scenarios from the early period of the big bang to current stellar evolution being a unique messenger of the fusio…
Evaluating approximate asymptotic distributions for fast neutrino flavor conversions in a periodic 1D box
Zewei Xiong, Meng-Ru Wu, Sajad Abbar +3
The fast flavor conversions (FFCs) of neutrinos generally exist in core-collapse supernovae and binary neutron-star merger remnants, and can significantly change the flavor composi…
A fast radio burst localized at detection to an edge-on galaxy using very-long-baseline interferometry
Tomas Cassanelli, Calvin Leung, Pranav Sanghavi +48
Fast radio bursts (FRBs) are millisecond-duration, luminous radio transients of extragalactic origin. These events have been used to trace the baryonic structure of the Universe us…
The Radio Parallax of the Crab Pulsar: A First VLBI Measurement Calibrated with Giant Pulses
Rebecca Lin, Marten H. van Kerkwijk, Franz Kirsten +2
We use four observations with the European VLBI network to measure the first precise radio parallax of the Crab Pulsar. We found two in-beam extragalactic sources just outside the…
R-process beta-decay neutrino flux from binary neutron star mergers and collapsars
Yu An, Meng-Ru Wu, Gang Guo +3
This study investigates the antineutrinos production by -decay of -process nuclei in two astrophysical sites that are capable of producing gamma-ray bursts (GRBs): binary neu…
How do supernova remnants cool? -- I. Morphology, optical emission lines, and shocks
Ekaterina I. Makarenko, Stefanie Walch, Seamus D. Clarke +4
Supernovae (SNe) inject erg in the interstellar medium, thereby shocking and heating the gas. A substantial fraction of this energy is later lost via radiative cooli…
Testing the linear relationship between black hole mass and variability timescale in low-luminosity AGN at submillimeter wavelengths
