“Astronarium” broadcast

Prof. Agnieszka Janiuk participated in the recording of the “Astronarium” series episode. It was devoted to the scientific purpose of launching the new satellite by ESA – mission “Athena”.  One of its objectives is to study transient energetic phenomena in the Universe, such a gamma ray bursts. The episode has been broadcasted in Polish TV channel TVP3 on February 7th. Now it is available on youtube, under this link.

Code HARM-COOL Public version

We are pleased to release for the first time the public version of our code HARM-COOL.
The code was built upon the HARM-2D General Relativistic scheme for magneto-hydrodynamical simulations for black hole accretion.
It was extensively upgraded and supplied with novel functionality.
This version, as of 2019, was developed since 2012, by Agnieszka Janiuk, Ireneusz Janiuk, and Kostas Sapountzis.
The source code is available here from the site “Numerics”.
One can find there also the README file with technical details.

Polish Society on Relativity conference

On September 23-26 in Szczecin, at the Maritime Academy, the Polish Society on Relativity PoToR held its 6th meeting. Among the invited speakers, we had a pleasure to hear lectures given by the leading specialists in the relativistic astrophysics discipline: prof. Masaru Shibata (Yukawa Institute, Kyoto, Japan), prof. Jose Font (University of Valencia, Spain), oraz prof. Tsvi Piran (Hebrew Univ., Jerusalem, Israel).
From CTP PAS, Agnieszka Janiuk presented selected talk on “Magnetized outflows from accreting black holes after neutron star merger”, and Ishika Palit presented a contribution in the parallel session, entitled „Accretion in a dynamical spacetime and the spinning up of the black hole in collapsars”.
