The 700 ks Chandra Spiderweb Field II: Evidence for inverse-Compton and thermal diffuse emission in the Spiderweb galaxy
P. Tozzi, R. Gilli, A. Liu +22
We present the X-ray imaging and spectral analysis of the diffuse emission around the Spiderweb galaxy at z=2.16 and of its nuclear emission, based on a deep (700 ks) Chandra obser…
V4745 Sgr -- a nova above the period gap and an intermediate polar candidate
Andrej Dobrotka, Alon Retter, Alex Liu
A period analysis of CCD unfiltered photometry of V4745 Sgr (Nova Sgr 2003 #1) performed during 23 nights in the years 2003 - 2005 is presented. The photometric data are modulated…
Nova V4743 Sagittarii 2002: An Intermediate Polar Candidate
Tae W. Kang, Alon Retter, Alex Liu +1
We present the results of 11 nights of CCD unfiltered photometry of V4743 Sgr (Nova Sgr 2002 # 3) from 2003 and 2005. We find two periods of 0.2799 d ~ 6.7 h and 0.01642 d ~ 24 min…
Detection of orbital and superhump periods in Nova V2574 Ophiuchi (2004)
Tae W. Kang, Alon Retter, Alex Liu +1
We present the results of 37 nights of CCD unfiltered photometry of nova V2574 Oph (2004) from 2004 and 2005. We find two periods of 0.14164 d (~3.40 h) and 0.14773 d (~3.55 h) in…
The orbital period of Nova V2540 Ophiuchi (2002)
T. Ak, A. Retter, A. Liu
We present the results of 26 nights of CCD photometry of the nova V2540 Oph (2002) from 2003 and 2004. We find a period of 0.284781 +/- 0.000006 d (6.8347 +/- 0.0001 h) in the data…
A photometric study of the newly discovered eclipsing cataclysmic variable SDSS J040714.78-064425.1
T. Ak, A. Retter, A. Liu +1
We present the results obtained from unfiltered photometric CCD observations of the newly discovered cataclysmic variable SDSS J040714.78-064425.1 made during 7 nights in November…
