... 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. ... For the full set of proposal instructions and requirements, see the FY16 Frontier Fields Lensing Map Call for Proposals....

... In the presence of only uniform magnetic field B , the motion of a charged particle can be described with gyration about the guiding center and motion along the field line. ... In the precence of both magnetic and electric fields, the equation of motion for charged particle (mass m, charge q) is m d v /dt = q ( E + v x B ). ... Because v is independent of the mass and sign of the charge, it is the same for negatively and positively charged particles, and does not create electric current. ...

... A second method to account for illumination problems in the flat fields is to remove the large scale pattern from the flat field itself. This is useful if there are no reasonable blank sky calibration frames and the astronomical exposures are evenly illuminated but the flat fields are not. ... Obviously, after having obtained the illumination corrected flat field it is reasonable to replace the original flat fields by the corrected flat fields in the reduction table. ...

... Bit Fields . Bit Fields: Practical Example . ... NOTE: The combination of pointers and bit-level operators makes C useful for many low level applications and can almost replace assembly code. ... To illustrate many points of bitwise operators let us write a function, Bitcount , that counts bits set to 1 in an 8 bit number ( unsigned char ) passed as an argument to the function. int bitcount(unsigned char x) { int count; for (count=0; x != 0; x>>=1); if ( x & 01) count++; return count; } . ...

... 2 Magnetic Field . ... A magnetized bar has its power concentrated at two ends, its poles ; they are known as its north (N) and south (S) poles, because if the bar is hung by its middle from a string, its N end tends to point northwards and its S end southwards. ... That flow became known as an electric current . ... An electric current produced a magnetic force! ... The fundamental nature of magnetism was not associated with magnetic poles or iron magnets, but with electric currents . ...

... Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: The role of magnetic fields in the intermediate-mass star formation process . ... Spectropolarimetric observations of Herbig Ae/Be stars indicate that magnetic fields are important ingredients of intermediate mass star formation. To properly understand the physics involved in the intermediate mass star formation process, it is particularly important to know the origin of the magnetic fields in these stars. ...
