... We employ Bayesian inference for the joint estimation of sources and background on ROSAT All-Sky Survey (RASS) data. ... Background maps were estimated in a single step together with the detection of sources without pixel censoring. ... The source probability is evaluated for single pixels as well as for pixel domains to enhance source detection of weak and extended sources. ... The spline fits the background component whereas count enhancements classify pixel (domains) with source contributions. ...

I would like to propose two new features for the axes annotation in the GMT. 1st: In astrophysics, we often work with great ranges of values (many orders of magnitude). ... However, GMT 3.2 allows to plot annotations for log10 axes every integer log10 value or even more frequently. The proposed patch allows to specify large steps for the log10 axes, in the form illustrated by an example below. 2nd: 10^0 instead of 1, and 10^1 instead of simply 10 do not look beautiful. ... The patch is here. ...

... We have observed and studied critical supercurrents, Ic, in cross-type Nb-Cu/Ni-Nb junctions with Josephson layers prepared from diluted ferromagnetic alloys. For suitable values of the exchange energy in the ferromagnet and the F-layer thickness we have observed Ic(T) oscillation with vanishing Ic for the definite values of T and dF. ... Critical supercurrents, Ic, in Nb-Cu(1-x)Ni(x)-Nb Josephson SFS junctions with F-layers prepared from ferromagnetic Cu(1-x)Ni(x) alloys have been studied. ...

home education > sharing the universe . ... Some social researchers who study how people spend their free time classify amateur astronomers and other amateur scientists as members of the " serious leisure " world, meaning their dedication to their favorite science does not constitute a hobby meant to simply pass the time, but is instead an earnest pursuit for knowledge and understanding. ... We also know that many amateur astronomers regularly engage in education and public outreach (EPO) activities. ...
