We report the results of our observations of the nebular complex MH9/10/11, associated with the ULX HoIX X-1, with scanning Fabry-Perot Interferometer. Two regions differing by their kinematics and line ratios may be distinguished, roughly corresponding to the bubble nebula MH9/10 and fainter HII-region MH11. For MH9/10 we find the expansion rate of 20-70km/s that is different for the approaching and receding parts. MH11 is characterised by very low velocity dispersion (less than or about 15km/s) and nearly constant line-of-sight velocities. Properties of MH11 may be explained by photoionization of gas with hydrogen density of about 0.2cm^-3. Luminosity required for that should be of the order of 10^39erg/s. Similar power source is required to explain the expansion rate of MH9/10. Modelling results also indicate that oxygen abundance in MH11 is about solar.
We present the results of high velocity and high spatial resolution HI synthesis observations of the blue compact dwarf galaxy IZw18 to investigate the link between its unique evolutionary history and the neutral gas distribution and kinematics. The
While protoplanetary disks often appear to be compact and well-organized in millimeter continuum emission, CO spectral line observations are increasingly revealing complex behavior at large distances from the host star. We present deep ALMA maps of t
We report on the 2017 September 10 ground level enhancement (GLE) event associated with a coronal mass ejection (CME) whose initial acceleration (~9.1km s^-2) and initial speed (~4300 km/s) were among the highest observed in the SOHO era. The GLE eve
Mid infrared (MIR) photonics is a key region for molecular physics [1]. High-resolution spectroscopy in the 1--10 {mu}m region, though, has never been fully tackled for the lack of widely-tunable and practical light sources. Indeed, all solutions pro
We present the new constraints on the cosmic optical background (COB) obtained from an analysis of the Pioneer 10/11 Imaging Photopolarimeter (IPP) data. After careful examination of data quality, the usable measurements free from the zodiacal light
