Partial Solar eclipse from Golovec Observatory

Partial Solar eclipse from Golovec Observatory

On 20 March 2015 a partial Solar eclipse was visible also from Slovenia. During this event the Astronomy group organized observations at Golovec Observatory for colleagues and students from the Faculty of mathematics and physics. Participants had the opportunity to observe the partial Solar eclipse using two telescopes (Skywatcher and Celestron) both equipped with Solar filters.

The bottom picture was shot during the phase of maximum coverage with DSLR Canon EOS 700D camera mounted on the 25-cm Newton telescope (foto by Herman Mikuž). The animation of the entire partial eclipse (composed by 87 photos) is visible at this link (animation by H. Mikuž and B. Dintinjana).

At the 9th conference on basic research in physics, a bi-annual event organized by our Faculty, which took place in Škofja Loka on 12ve of November 2014, assist. prof. dr. Andreja Gomboc had an invited lecture on “Observations of most powerful explosions in the Universe with telescopes in visible light”, while dr. Dunja Fabjan presented a talk on “The Sunjajev-Zeldovich effect in cosmological simulations of galaxy clusters”.

Most notable research achievements in 2014

 

Traditional Week of the University of Ljubljana for the first time started with a presentation of ten most notable research achievements of the University of Ljubljana in the year 2014. The opening event of the week on Monday, December 1 2014 included presentations of two achievements contributed by members of the astronomy research group: assist. prof. dr. Andreja Gomboc, dr. Drejc Kopač and dr. Jure Japelj (Investigations of the most powerful explosions in the Universe) and prof. dr. Tomaž Zwitter and Janez Kos (Spatial maps of diffuse interstellar band at 862 nanometers). Another featured achievement from another researcher of our Faculty of Mathematics and Physics was the one of assoc. prof. Primož Ziherl (Mosaic quasi-cristals). Details can be found here. Congratulations!

Excellence in science 2013

On Thursday, December 11 2014, the Slovenian Research Agency organized the event Excellence in Science 2013 where the scientific achievements from the area of natural sciences and mathematics have been presented. Member of our research team dr. Jure Japelj had a short presentation at the event. He spoke on highly polarized light originating from ordered magnetic fields in the gamma ray burst 120308A. Congratulations to everybody achieving excellence in science!

Infall of asteroids into a black hole

Infall of asteroids into a black hole

Chandra X-ray observatory published a press release that the misterious X-ray flares from the Galactic center are due to infall of asteroids into the supermassive black hole lurking at the center of our Galaxy.

The work of Zubovas et al. was the reason for posting the news, however, the astrophysicists from the Faculty of Mathematics and Physics, University of Ljubljana, have already proposed this mechanism for X-ray flares, many years before Zubovas et al. For this reason we were invited by the Chandra Blog team, to write a blog posting on the subject.
