Spirals and clumps in V960 Mon: signs of planet formation via gravitational instability around an FU Ori star?

Autor: Weber, P., Pérez, S., Zurlo, A., Miley, J., Hales, A., Cieza, L., Principe, D., Cárcamo, M., Garufi, A., Kóspál, Á., Takami, M., Kastner, J., Zhu, Z., Williams, J.

The formation of giant planets has traditionally been divided into two pathways: core accretion and gravitational instability. However, in recent years, gravitational instability has become less favored, primarily due to the scarcity of observations

Multi-GPU maximum entropy image synthesis for radio astronomy

Autor: Cárcamo, M., Román, P., Casassus, S., Moral, V., Rannou, F. R.

Publikováno v: M. C\'arcamo, P.E. Rom\'an, S. Casassus, V. Moral, F.R. Rannou, Multi-GPU maximum entropy image synthesis for radio astronomy, Astronomy and Computing, Volume 22, 2018, Pages 16-27, ISSN 2213-1337

The maximum entropy method (MEM) is a well known deconvolution technique in radio-interferometry. This method solves a non-linear optimization problem with an entropy regularization term. Other heuristics such as CLEAN are faster but highly user depe

A compressed sensing faraday depth reconstruction framework for the MeerKAT MIGHTEE-POL Survey

Autor: Cárcamo, M, Scaife, A, Taylor, R, Jarvis, M, Bowles, M, Sekhar, S, Heino, L, Stil, J

In this work we present a novel compute framework for reconstructing Faraday depth signals from noisy and incomplete spectro-polarimetric radio datasets. This framework is based on a compressed-sensing approach that addresses a number of outstanding
