در بررسی­های فونستیک سال 2011 دامنه جنوبی رشته کوه­های زاگرس ایران، یک نمونه ماده از گونه Amphipyra kautti Hacker, 2002 متعلق به خانواده Noctuidae و زیرخانواده Amphipyrinae مناطق کوهستانی استان کهگیلویه بویراحمد جمع­ آوری شناسایی شد. این که برای اولین بار ایران گزارش می­شود، همراه با ویژگی­های افتراقی، تصویر الگوی بال اندام تناسلی شده ارائه است. اطلاعات مربوط دیگر همین جنس مطالعه نیز

In this paper, we present high time-resolution observations of GW Librae (GW Lib) and SDSS J161033.64−010223.3 (SDSS 1610) – two cataclysmic variables which have shown periodic variations attributed to non-radial pulsations of the white dwarf (WD). We observed both these systems in their quiescent states with ULTRACAM on the Very Large Telescope (VLT) and the University of Cape Town Photometer ...

We present high time-resolution multicolour observations of the quiescent soft Xray transient V404Cyg obtained with ULTRACAM . Superimposed on the secondary star’s ellipsoidal modulation are large flares on timescales of a few hours, as well as several distinct rapid flares on timescales of tens of mins. The rapid flares, most of which show further variability and unresolved peaks, cover shorte...

The large digital frame camera UltraCamX was introduced in 2006 by Vexcel Imaging (a Microsoft Company). This paper will give a short technical overview about the concept of the camera and more information on the radiometric quality of the UltraCamX. The focus in this paper is set on the radiometric quality of the sensors. Already recorded image data are analyzed in detail for their radiometric...

We have measured the X-ray/optical cross-correlation functions (CCFs) of the two black hole binary systems SWIFT J1753.5−0127 and GX 339−4 using ULTRACAM and RXTE. We find each one is unique and different from the one such measurement in the literature, for XTE J1118+480. Our CCFs are inconsistent with reprocessing, and suggest a mechanism which regulates emission between the different spectral...
