Exploring the nature of radio relics and halos in galaxy clusters through GHz radio observations
(2015-09-02)
Clusters of galaxies are the largest gravitationally bound systems in the Universe. A fraction of them hosts diffuse Mpc-scale synchrotron sources (referred to as radio relics and radio halos) not related to any discrete ...
The Optical System and the Astronomical Potential of A-MKID, a New Camera Using Microwave Kinetic Inductance Detector Technology
(2015-11-25)
In the framework of sub-millimeter astronomy, the need to create more efficient cameras with more pixels, with larger FoV and with higher mapping speed is highly desirable. In order to satisfy this necessity a new camera ...
Starburst clusters in the Galactic center
(2015-07-07)
The central region of the Galaxy is the most active site of star formation in the Milky Way, where massive stars have formed very recently and are still forming today. The rich population of massive stars in the Galactic ......
The APEX submillimeter imaging survey of distant galaxies in the COSMOS field
(2015-11-16)
Submillimeter galaxies (SMGs) are far-infrared luminous, vigorously star forming galaxies in the early universe. They are major contributors to the extragalactic far-infrared background emission, and they trace the most ...
Investigating Anisotropies in the Local Universe with Type Ia Supernovae from the Nearby Supernova Factory
(2015-12-10)
The dipole anisotropy of the cosmic microwave background temperature is two orders of magnitude larger than its other multipole components, which is attributed to the Doppler shift due to the motion of our Local Group of ...
Automated Source Extraction for the Next Generation of Neutral Hydrogen Surveys
(2015-12-23)
This thesis is a first step to develop the necessary tools to automatically extract and parameterize sources from future HI surveys with ASKAP, WSRT/Apertif, and SKA.
The current approach to large-scale HI surveys, ...

Detailed X-ray properties of galaxy groups and fossil groups
(2015-09-16)
Most galaxies in the Universe are aggregated into groups of galaxies, agglomerations of a few 10s of galaxies at most. For long they have been considered to be very similar to clusters, which contain a few 100s of galaxies. ...
