Chromospheric emission of solar-type stars with asteroseismic ages
R S Booth, K. Poppenhaeger, C. A. Watson +3
Stellar magnetic activity decays over the main-sequence life of cool stars due to the stellar spin-down driven by magnetic braking. The evolution of chromospheric emission is well-…
Inflation of 430-parsec bipolar radio bubbles in the Galactic Centre by an energetic event
I. Heywood, F. Camilo, W. D. Cotton +96
The Galactic Centre contains a supermassive black hole with a mass of 4 million suns within an environment that differs markedly from that of the Galactic disk. While the black hol…
Revival of the magnetar PSR J1622-4950: observations with MeerKAT, Parkes, XMM-Newton, Swift, Chandra, and NuSTAR
F. Camilo, P. Scholz, M. Serylak +205
New radio (MeerKAT and Parkes) and X-ray (XMM-Newton, Swift, Chandra, and NuSTAR) observations of PSR J1622-4950 indicate that the magnetar, in a quiescent state since at least ear…
An Overview of the MHONGOOSE Survey: Observing Nearby Galaxies with MeerKAT
W. J. G. de Blok, E. A. K. Adams, P. Amram +65
MHONGOOSE is a deep survey of the neutral hydrogen distribution in a representative sample of 30 nearby disk and dwarf galaxies with HI masses from 10^6 to ~10^{11} M_sun, and lumi…
An Improved Age-Activity Relationship for Cool Stars older than a Gigayear
R. S. Booth, K. Poppenhaeger, C. A. Watson +2
Stars with convective envelopes display magnetic activity, which decreases over time due to the magnetic braking of the star. This age-dependence of magnetic activity is well-studi…
Engineering and Science Highlights of the KAT-7 Radio Telescope
A. R. Foley, T. Alberts, R P. Armstrong +100
The construction of the KAT-7 array in the Karoo region of the Northern Cape in South Africa was intended primarily as an engineering prototype for technologies and techniques appl…
