ALMA High-frequency Long-baseline Campaign in 2017: A Comparison of the Band-to-band and In-band Phase Calibration Techniques and Phase-calibrator Separation Angles

Luke T. Maud, Yoshiharu Asaki, Edward B. Fomalont +9

The Atacama Large millimeter/submillimeter Array (ALMA) obtains spatial resolutions of 15 to 5 milli-arcsecond (mas) at 275-950GHz (0.87-0.32mm) with 16km baselines. Calibration at…

The auroral radio emission of the magnetic B-type star rho OphC

P. Leto, C. Trigilio, C. S. Buemi +19

The non-thermal radio emission of main-sequence early-type stars is a signature of stellar magnetism. We present multi-wavelength (1.6-16.7 GHz) ATCA measurements of the early-type…

Evidence for radio and X-ray auroral emissions from the magnetic B-type star rho Oph A

P. Leto, C. Trigilio, F. Leone +20

We present new ATCA multi-wavelength radio measurements (range 2.1-21.2 GHz) of the early-type magnetic star rho Oph A, performed in March 2019 during 3 different observing session…
