Kavli Affiliate: George Efstathiou | First 5 Authors: Marta Spinelli, Gianni Bernardi, Hugh Garsden, Lincoln J. Greehill, Anastasia Fialkov | Summary: Total-power radiometry with individual meter-wave antennas is a potentially effective way to study the Cosmic Dawn ($zsim20$) through measurement of sky brightness arising from the $21$~cm transition of neutral hydrogen, provided this can be […]

On the Circular Polarisation of Repeating Fast Radio Bursts

Posted by klaurent Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Shi Dai, Jiguang Lu, Chen Wang, Weiyang Wang, Renxin Xu | Summary: Fast spinning (e.g., sub-second) neutron star with ultra-strong magnetic fields (or so-called magnetar) is one of the promising origins of repeating fast radio bursts (FRBs). Here we discuss circularly polarised emissions produced by propagation effects […]
