Particle Acceleration in Stratified 2D MRI Turbulence: From Reconnection to First- and Second-Order Fermi and Shear Acceleration
Astor Sandoval, Mario Riquelme, Jorge Cuadra
Low-luminosity accretion disks around black holes are weakly collisional, potentially enabling nonthermal particle acceleration. Local two-dimensional particle-in-cell simulations…
Discovery of a star sensitive to the spin of Sgr A*
K. Abd El Dayem, R. Abuter, N. Aimar +85
Residing in the center of the Milky Way, Sgr A* is the closest massive black hole (MBH). Its vicinity has allowed measuring individual stellar orbits around it. The stars act as te…
Resolving the Binary Components of the Outbursting Protostar HBC 494 with ALMA
Pedro Henrique Nogueira, Alice Zurlo, Sebastián Pérez +15
Episodic accretion is a low-mass pre-main sequence phenomenon characterized by sudden outbursts of enhanced accretion. These objects are classified into two: protostars with elevat…
The Asymmetric Sunrise Effect on Thales' Alleged Measurement of the Sun Angular Size
Jorge Cuadra
Reports from the 2nd and 3rd Century AD attribute the first measurement of the angular size of the Sun to Thales of Miletus, in the 6th Century BC. Cleomedes, also in the 2nd Centu…
Protoplanet Express, a video game based on numerical simulations
Jorge Cuadra, Miguel Vergara, Bruno Escárate +2
Astronomical images can be fascinating to the general public, but the interaction is typically limited to contemplation. Numerical simulations of astronomical systems do permit a c…
Infrared variability of young solar analogs in the Lagoon Nebula
C. Ordenes-Huanca, M. Zoccali, A. Bayo +9
T Tauri stars are low-mass pre-main sequence stars that are intrinsically variable. Due to the intense magnetic fields they possess, they develop dark spots on their surface that,…
