A Deep Search with Hst for Late Time Supernova Signatures in the Hosts of Xrf 011030 and Xrf 020427
X-ray Flashes (XRFs) are, like Gamma-Ray Bursts (GRBs), thought to signal the collapse of massive stars in distant galaxies. Many models posit that the isotropic equivalent energies of XRFs are lower than those for GRBs, such that they are visible from a reduced range of distances when compared with GRBs. Here we present the results of two epoch Hubble Space Telescope imaging of two XRFs. These...
متن کامل3 The First Two Host Galaxies of X - ray Flashes : XRF 011030 and XRF 020427
Given the paucity of empirical constraints, the nature of the newly-recognized phenomena called X-Ray Flashes (XRFs) has been an open question. However, with the recent detections of radio and X-ray afterglow it is finally possible to study the large-and small-scale environments of XRFs. We present Chandra, Hubble Space Telescope (HST), and Keck observations of the fields of XRFs 011030 and 020...
متن کاملLong-term flaring activity of XRF 011030 observed with BeppoSAX
We present the spectral and temporal analysis of the X-ray flash XRF 011030 observed with BeppoSAX. This event is characterized by a very long X–ray bursting activity that lasts about 1500 s, one of the longest ever observed by BeppoSAX. In particular, a precursor and a late flare are present in the light curve. We connect the late X–ray flare observed at about 1300 s to the afterglow emission ...

متن کاملDeep multilayer gratings with adjustable bandpass for XRF spectroscopy
We propose here a deep multilayer grating with adjustable bandpass as an alternative dispersing element to PET crystal in WDXRF spectroscopy. When making a multilayer grating, we remove part of the reflecting planes of a multilayer, allowing radiation to penetrate deeper. Since the resolution, or the bandpass, is reciprocally proportional to the penetration depth, we improve the resolution and ...
