Our group member Oğuzhan Çakır got accepted from Macquarie University for the PhD program. Mr. Çakır awarded with theInternational Research Training Program Scholarship (iRTP) which is the most prestigious scholarship for foreign students that is given by the Commonwealth Government of Australia.He will conduct studies on galaxy clusters that were surveyed within the framework of SAMI and Hector Surveys.His research project will be supervised under theResearch Centre for Astronomy, Astrophysics and Astrophotonics of the Macquarie University.We congratulate our dear Oğuzhan and wish all the best for his PhD studies.

Research Asist. Süleyman Fişek was assigned to Atatürk University to work in The “Eastern Anatolia Observatory” (DAG) Project for a year.

Our group member Süleyman Fişek, due to his doctoral studies on the DAG Telescope and the installation of the telescope, temporarily left to work at Atatürk University Astrophysics Application and Research Center (ATASAM). He will work on integration of adaptive optics system and infrared sky measurements for the DAG telescope. We wish best to Mr. Fişek, who will also take part in the first light studies of the DAG Telescope.

Collaborating with Dr. Tomotsugu Goto from NTHU

Our group has started to collaborate with Dr. Tomotsugu Goto and his group from National Tsing Hua University, Taiwan. Thanks to our group leader Dr. Sinan Aliş’s initiative and the support of Scientific and Technological Research Council of Turkey (TÜBİTAK), Dr. Goto also visited our Astronomy Dept. and gave a talk named “Revealing cosmic star formation history and black hole accretion history with the AKARI space telescope and the Subaru telescope’s new Hyper-Suprime Camera”.

Our group and Dr. Goto’s group has started to work together on evolution of galaxies in galaxy cluster by using Subaru HSC-SSP survey obtained from Subaru Telescope which is located in Mauna Kea in Hawaii. Our new collaboration will continue with some new researches on extra-galactic astronomy and will give the groups to do some graduate students exchanges as well.

XXL Hunt for Galaxy Clusters

Leave a comment

This image shows XXL-South Field (or XXL-S), one of the two fields observed by the XXL survey. XXL is one of the largest quests for galaxy clusters ever undertaken and provides by far the best view of the deep X-ray sky yet obtained. The survey was carried out with ESA’s XMM-Newton X-ray observatory. Additional vital observations to measure the distances to the galaxy clusters were made with ESO facilities. The area shown in this image was obtained with some 220 XMM-Newton pointings and, if viewed on the sky, would have a two dimensional area a hundred times larger than the full Moon (which spans one half degree), and that is without taking into account the depth that the survey explores. The red circles in this image show the clusters of galaxies detected in the survey. Along with the other field — XXL-North Field (or XXL-N) — around 450 of these clusters were uncovered in the survey, which mapped them back to a time when the Universe was just half of its present age. The image also reveals some of the 12 000 galaxies that had very bright cores containing supermassive black holes that were detected in the field.

XXL is an international project based around an XMM Very Large Programme surveying two 25 square degrees extragalactic fields. Optical observations for XXL from ESO telescopes (VLT and the NTT) provide crucial third dimension in probe of Universe’s dark side. The XXL survey is expected to produce many exciting and unexpected results.

Dr. Sinan Aliş,  is one of the team members in the project XXL.
