The Synchrotron Low-Energy Spectrum Arising from the Cooling of Electrons in Gamma-Ray Bursts
A. D. Panaitescu, W. T. Vestrand
This work is a continuation of a previous effort (Panaitescu 2019) to study the cooling of relativistic electrons through radiation (synchrotron and self-Compton) emission and adia…
Properties of the Prompt Optical Counterpart Arising from the Cooling of Electrons in Gamma-Ray Bursts
A. D. Panaitescu, W. T. Vestrand
This work extends a contemporaneous effort (Panaitescu & Vestrand 2022) to study the properties of the lower-energy counterpart synchrotron emission produced by the cooling of rela…
Synchrotron and inverse-Compton emissions from pairs formed in GRB afterglows (analytical treatment)
A. Panaitescu
We calculate the synchrotron and inverse-Compton emissions from pairs formed in GRB afterglows from high-energy photons (above 100 MeV), assuming a power-law photon spectrum C_nu ~…
GRB 081008: from burst to afterglow and the transition phase in between
F. Yuan, P. Schady, J. L. Racusin +30
We present a multi-wavelength study of GRB 081008, at redshift 1.967, by Swift, ROTSE-III and GROND. Compared to other Swift GRBs, GRB 081008 has a typical gamma-ray isotropic equi…
Probing the Pulsar Wind Nebula of PSR B0355+54
Katherine E. McGowan, W. Tom Vestrand, Jamie A. Kennea +3
We present XMM-Newton and Chandra X-ray observations of the middle-aged radio pulsar PSR B0355+54. Our X-ray observations reveal emission not only from the pulsar itself, but also…
Northern Sky Variability Survey (NSVS): Public data release
P. R. Wozniak, W. T. Vestrand, C. W. Akerlof +15
The Northern Sky Variability Survey (NSVS) is a temporal record of the sky over the optical magnitude range from 8 to 15.5. It was conducted in the course of the first generation R…
Detection of Pulsed X-ray Emission from XMM-Newton Observations of PSR J0538+2817
Katherine E. McGowan, Jamie A. Kennea, Silvia Zane +5
We report on the XMM-Newton observations of the 143 ms pulsar PSR J0538+2817. We present evidence for the first detections of pulsed X-rays from the source at a frequency which is…
High Resolution Soft X-ray Spectroscopy of M87 with the Reflection Grating Spectrometers on XMM-Newton
I. Sakelliou, J. R. Peterson, T. Tamura +11
We present high-resolution X-ray spectroscopic observations of M87 with the Reflection Grating Spectrometers on XMM-Newton. We detect strong K-shell line emission from N, O, Ne, Mg…
XMM-Newton observations of M87 and Its X-Ray Halo
H. Boehringer, E. Belsole, J. Kennea +10
We report performance verification observations of the giant elliptical galaxy M87 in the Virgo Cluster with the MOS, pn, and optical monitor instruments on board of XMM-Newton. Wi…
A Mosaic of the Coma Cluster of Galaxies with XMM-Newton
Ulrich G. Briel, J. Patrick Henry, David H. Lumb +7
The Coma cluster of galaxies was observed with XMM-Newton in 12 partially overlapping pointings. We present here the resulting X-ray map in different energy bands and discuss the l…
XMM- Newton Observation of the Coma Galaxy Cluster: The temperature structure in the central region
M. Arnaud, N. Aghanim, R. Gastaud +8
We present a temperature map and a temperature profile of the central part (r < 20' or 1/4 virial radius) of the Coma cluster. We combined 5 overlapping pointings made with XMM/EPI…
