... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ...

... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...

The SAMI instrument on the AAT is currently taking integral field spectroscopy of ~3000 nearby galaxies as part of the SAMI Galaxy Survey. This is the largest sample ever across a broad range in both stellar mass and environment (from field galaxies to groups to clusters). Based on ionised gas and stellar kinematics in the SAMI galaxies, I will discuss the relationship between dynamical misalignments and the influence of environment, morphology and timescales on the origin of gas in galaxies. ...

... Research . ... There is mounting evidence that AGN feedback is important in galaxy evolution. Radio-mode feedback is thought to be particularly significant because the mechanical action of the expanding lobes provides a strong coupling mechanism between AGN energy and the surrounding environment. In order to quantify this feedback, detailed models of radio lobe evolution are required. ... Cambridge, UK - Nov 2013 . PDF . Poster for Modern Radio Universe conference . ...

... The ring current (e.g., Frank, 1967) consists of geomagnetically trapped 10 - 200 keV ions (mainly H + , He + , and O + ) and electrons that drift azimuthally around the Earth at radial distances of about 2-7 Re (Earth radii), overlapping the radiation belt region. ... This index can be used to monitor the development of geomagnetic storm (see also geomagnetic activity ), as the main signature (actually definition) of the storm main phase is the build-up of an enhanced ring current. ...

... Compact Binaries . ... Unlike the Sun, most stars in our Galaxy orbit another star: these systems are called binary stars. Generally it takes many years for the two stars to orbit around each other. ... These binaries are interesting for many reasons. One is that they are predicted to emit lots of gravitational waves. ... Over time as gravitational waves are emitted, the time taken for the two stars to orbit one another changes by a small but measurable amount. ...
