Self-similar solutions of oscillatory reconnection: parameter study of magnetic field strength and background temperature

Autor: Schiavo, Luiz A. C. A., Botha, Gert J. J., McLaughlin, James A.

Publikováno v: ApJ 975 (2024) 10

Oscillatory reconnection is a specific type of time-dependent reconnection which involves periodic changes in the magnetic topology of a null point. The mechanism has been reported for a variety of magnetic field strengths and configurations, backgro

The $^{244}$Pu($^{50}$Ti,$xn$)$^{294-x}$Lv reaction was investigated at Lawrence Berkeley National Laboratory's 88-Inch Cyclotron facility. The experiment was aimed at the production of a superheavy element with $Z\ge 114$ by irradiating an actinide

The TruEnd-procedure: Treating trailing zero-valued balances in credit data

Autor: Botha, Arno, Verster, Tanja, Bester, Roelinde

A novel procedure is presented for finding the true but latent endpoints within the repayment histories of individual loans. The monthly observations beyond these true endpoints are false, largely due to operational failures that delay account closur

The Effect of Resistivity on the Periodicity of Oscillatory Reconnection

Autor: Talbot, Jordan, McLaughlin, James A., Botha, Gert J. J., Hancock, Mark

The oscillatory reconnection mechanism is investigated for a parameter study of eight orders of magnitude of resistivity, with a particular interest in the evolution of the oscillating current density at the null point and its associated periodicity.

We present the SARAO MeerKAT Galactic Plane Survey (SMGPS), a 1.3 GHz continuum survey of almost half of the Galactic Plane (251\deg $\le l \le$ 358\deg and 2\deg $\le l \le$ 61\deg at $|b| \le 1.5\deg $). SMGPS is the largest, most sensitive and hig
