Simultaneous optical and radio observations of Perseids

From today (August 11th) up until Friday the yearly Perseids meteor shower will have its peak. This phenomenon is not only interesting for amateur astronomers, professional astronomers will be observing them as well.

Colloquium: Eli Pattie

X-ray binaries, or accreting black holes and neutron stars, host some of the most extreme environments in the Universe. Jets are one of the main components of X-ray binaries, and they are fed material by the accretion flow and believed to be collimated and accelerated by magnetic fields in the vicinity of the accretor, though there is much that is yet to be understood. The X-ray binary jet paradigm was developed based on observations and theories of accreting black holes, and the extent to which this also applies to accreting neutron star jets is debated. In this talk I will focus on these neutron star X-ray binary jets, presenting recent high sensitivity radio observations of multiple systems that reveal detailed information regarding their jet behaviors such as variability, spectral, and polarization properties, and discuss how these compare to black hole jets. Neutron star accretion is more complex than black holes due to their solid surfaces and intrinsic magnetic fields, and some of these differences may manifest in their jet behaviors as well, thus additionally allowing us to investigate their overall accretion behaviors by studying their jets.
