... As an application I discuss the magnetic field amplification in a young galaxy, where turbulence is driven by accretion and supernova explosions. ...
... I will give an overview of the Mega-SH0ES project and the techniques it is using, including the Parallel Astrometric Spatial Scanning (PASS) on WFC3, Infrared Cepheids, and 17 New Type Ia Supernova host galaxies. ...
... To set up your simulation, assume that H0 = 70 km/s/Mpc (and ignore effects M , ) and that the absolute magnitude of SN Ia =-19.5 mag, and that your supernova search will be able to detect a 100% of objects as faint as 18.5 magnitude, and none fainter. ...
... Now the range of subject matter is very broad and includes supernova remnants, the hot atmospheres of elliptical galaxies, radio galaxies, quasars, jets, black holes and gamma-ray bursters. ...
... spatial resolution of HST separates each supernova from its host galaxy and leads to ... that allows the measurement of supernova (SN) properties at large distances ...
... supernova remnants Take relationship between r E ----- 1 / 5 t 2 / 5 r= 0 The locus of the outgoing blast wave is given by = 1 (66) (65) Astrophysical Gas Dynamics: Bubbles 50/53 Knowing the radius of the blast wave and the time we can calculate the ...
... most directly probed by using type 1a supernova (SN1a) as standard candles (Riess et ... 2007; Wood-Vasey et al. 2007) < > include supernova from redshifts z 1.8 (a 0.36). ...

... It is highly variable, and is a strong candidate for a supernova explosion. ... The most distant supernova seen is more than halfway back to the Big Bang, and thus ...
... Using M86 you can then calibrate the supernova distance scale, and find the distances to M12, NFC64 and B3 with high accuracy. ... The enormous supernova distance to B3 supports this suggestion, by placing B3 far behind the GMS. ...
... GRBs.22 5 Limits on an associated supernova At z = 0.16, the distance mo dulus of ... are consistent with a pure afterglow evolution, and show no evidence for a supernova ...
