The XMM-Newton Detection of Extended Emission from the Nova Remnant of T Pyxidis (2010)
We report the detection of an extended X-ray nebulosity with an elongation from northeast to southwest in excess of 15$^{\prime\prime}$ in a radial profile and imaging of the recurrent nova T Pyx...
We present the broad-band noise structure of selected Anomalous X-Ray Pulsars (AXPs) and Soft Gamma Repeaters (SGRs) in the 2-60 keV energy band. We have analyzed Rossi X-ray Timing Explorer...
An optical search for supernova remnants in the nearby spiral galaxy NGC 2903 (2009)
Sonbas, E., Akyuz, A., Balman, S.
We present the results of an optical search for supernova remnants (SNRs) in the nearby spiral galaxy NGC 2903. Interference filter images and spectral data were taken in March 2005 with the f/7.7...
Trigo, M. Diaz, Parmar, A. N., Boirin, L., Motch, C., Talavera, A., Balman, S.
We have analysed data from five XMM-Newton observations of XB 1254-69, one of them simultaneous with INTEGRAL, to investigate the mechanism responsible for the highly variable dips durations and...
RR Pic (1925): A Chandra X-ray View (2008)
We present the Chandra ACIS-S3 data of the old classical nova RR Pic (1925). The source has a count rate of 0.067+/-0.002 c/s in the 0.3-5.0 keV energy range. We detect the orbital period of the...

X-ray outburst of 4U 0115+634 and ROTSE Observations of its Optical Counterpart V635 Cas (2005)
Baykal, A., Kiziloglu, U., Kiziloglu, N., Balman, S., Inam, S. C.
ROTSE IIId (The Robotic Optical Transient Experiment) observations of X-ray binary system 4U 0115+634/V635 Cas obtained during 2004 June and 2005 January make possible, for the first time, to study...
Balman, S., Yilmaz, A., Retter, A., Saygac, T., Esenoglu, H., .
We present the CCD photometry, light curve and time series analysis of the classical nova V2275 Cyg (N Cyg 2001 No.2). The source was observed for 14 nights in total using an R filter in 2002 and...
Discovery of a New Transient Magnetar Candidate: XTE J1810-197 (2003)
Ibrahim, A. I., Markwardt, C., Swank, J., Ransom, S., Roberts, M., Kaspi, V., ...
We report the discovery of a new X-ray pulsar, XTE J1810-197. The source was serendipitously discovered on 2003 July 15 by the Rossi X-ray Timing Explorer (RXTE) while observing the soft gamma...
Ness, J. -U., Starrfield, S., Burwitz, V., Hauschildt, P., Wichmann, R., Drake, J. J., ...
V4743 Sgr (Nova Sgr 2002 No. 3) was discovered on 20 September 2002. We obtained a 5ks ACIS-S spectrum in November 2002 and found that the nova was faint in X-rays. We then obtained a 25ks CHANDRA...

CHANDRA Detection of 16 New X-Ray Sources (2002)
We have detected 18 sources over 6 sigma threshold within two regions 8.3X16.9 arcmin^2 and 8.3X33.6 arcmin^2 in the vicinity of the point with alpha=03h31m02.45s (J2000) and...
The analyses of X-ray emission from classical novae during the outburst stage have shown that the soft X-ray emission below 1 keV, which is thought to originate from the photosphere of the white...
The emission nebula associated with V1974 Cyg: a unique object? (2000)
Casalegno, R., Orio, M., Mathis, J., Conselice, C., Gallagher, J., Balman, S., ...
Through a program of narrow band imaging, we have observed the changing structure of the H alpha emission line around Nova Cyg 1992 (V1974 Cyg) at regular intervals from 1996 to 1999. Between 1994...
