Blank Field Sources in the ROSAT HRI Brera Multiscale Wavelet catalog
The search for Blank Field Sources (BFS), i.e. X-ray sources without optical counterparts, paves the way to the identification of unusual objects in the X-ray sky. Here we present four BFS detected in the Brera Multiscale Wavelet catalog of ROSAT HRI observations. This sample has been selected on the basis of source brightness, distance from possible counterparts at other wavelengths, point-lik...
متن کاملQuasars in the MAMBO blank field survey
Our MAMBO 1.2 mm blank field imaging survey of ∼ 0.75 sqd has uncovered four unusually bright sources, with flux densities between 10 and 90 mJy, all located in the Abell 2125 field. The three brightest are flat spectrum radio sources with bright optical and X-ray counterparts. Their mm and radio flux densities are variable on timescales of months. Their X-ray luminosities classify them as quas...
متن کاملA radio survey of supersoft, persistent and transient X-ray sources in the Magellanic Clouds
We present a radio survey of X-ray sources in the Large and Small Magellanic clouds with the Australia Telescope Compact Array at 6.3 and 3.5 cm. Specifically, we have observed the fields of five LMC and two SMC supersoft X-ray sources, the X-ray binaries LMC X-1, X-2, X-3 & X-4, the X-ray transient Nova SMC 1992, and the soft gamma-ray repeater SGR 0525-66. None of the targets are detected as ...
متن کاملPersistent memories in transient networks
Spatial awareness in mammals is based on an internalized representation of the environment, encoded by large networks of spiking neurons. While such representations can last for a long time, the underlying neuronal network is transient: neuronal cells die every day, synaptic connections appear and disappear, the networks constantly change their architecture due to various forms of synaptic and ...
متن کاملTransient and persistent serial correlations 1
Researchers in psychology are paying increasing attention to temporal correlations in performance on cognitive tasks. Recently, T. Thornton and D. L. Gilden (2005) introduced a spectral method for analysing psychological time series; in particular, this method is tailored to distinguish transient serial correlations from the persistent correlations characterised by 1/f noise. Thornton and Gilde...
