One of our students, Tugba Boztepe, has been selected as one of the fellows for the LEAPS program in Leiden University. She will be working for the project “How is galaxy color tied to dark matter?”, supervised by Mohammadjavad Vakili. The research project will take place from June 4th to August 10th, 2018 in Leiden, the Netherlands.
This project is about Galaxies, which are formed in collapsed structures known as dark matter halos. One of the common assumptions is that the properties of galaxies can be fully characterized by their host halo mass. At any given redshift, galaxies fall into two main groups: (1) blue and star forming galaxies, and (2) red or passively evolving (also known as quenched) galaxies. One of the outstanding questions in modern structure formation is whether galaxy properties are correlated with their large-scale environment. The quenched fraction of centrals (galaxies that reside in the center of halos) may be correlated with the large scale density at fixed halo mass. However, the existing results based on observations and simulations remain conflicting. This project aims to contribute to our understanding of structure formation by investigating the observational relation between the fraction of red (quenched) centrals and local density of galaxies in filaments, groups, and voids using the SDSS main galaxy catalog.
In cooperation with the DAG (Eastern Anatolia Observatory) 4-m telescope project and with the support of the Ministry of Development we have been working on preparing a laboratory for astronomical detector characterization and tests. The first stage of the project is now over, where our optical tables and some of the electronics are acquired together with the establishment of the laboratory at the Astronomy and Space Sciences Department building.
Two of our members (Kai Schwenzer and Tolga Guver) won prestigious Simons Foundation Fellowships to perform research and attend conferences at the Aspen Center for Physics Colorado USA.
Our members will go at different dates to the center during this summer to attend workshops “Neutron Stars: Linking Nuclear Physics of the Interior to Electromagnetic Observations and Gravitational Radiation” and “Astrophysics of Gravitational Radiation Sources and Multimessenger Astronomy in the Era of LIGO Detections” and also do research on astrophysics.
We invite you to submit an abstract for a contributed oral or poster presentation for Special Session SS6 “Exploring Neutron Star Structure by Timing and Spectroscopy” to be held during EWASS2017 in Prague, Czech Republic. Information about EWASS 2017 and our special session can be found at
