On the X - ray position and deep optical imaging of the neutron star candidate RXJ 1856 . 5 - 3754 ?
We present X-ray and optical studies of the ROSAT source RXJ1856.5-3754, a neutron star candidate. With recent optical observations of a potential optical counterpart to another X-ray source in the field and correcting the X-ray positions for two effects not taken into account before, we determine the ROSATX-ray source position and its error, both different from previous work. Also, we present ...
Bacillus amyloliquefaciens TF28 is a biocontrol endophytic bacterium that is capable of inhibition of a broad range of plant pathogenic fungi. The strain has the potential to be developed into a biocontrol agent for use in agriculture. Here we report the whole-genome shotgun sequence of the strain. The genome size of B. amyloliquefaciens TF28 is 3,987,635 bp which consists of 3754 protein-codin...
Recently there is a suggestion about the star RXJ1856.5−3754, being a possible candidate for quark star. While from the estimates of the radiation radius, given by the authors, it does not seem to fit with any of the known models for such stars, the mass radius diagram admits the possibility of this being a quark star of mass M ⊙ < M < 1.4M ⊙ , provided the radius mentioned is the actual radius...
Modified versions of two “standard” pulsar search techniques are presented that allow large-scale searches for pulsations in long duration high-energy data sets using relatively modest amounts of computer time. For small numbers of photons (Nphot ∼< 10 ), optimized brute-force epoch folding searches are preferred. For larger numbers of photons, advanced Fourier domain acceleration searches are ...
