چکیده
We present the results from multi-wavelength monitoring observations of Narrow-Line Seyfert 1 galaxy Mrk 335 with AstroSat. analysed both X-ray (SXT and LAXPC) UV (UVIT) data source at two epochs, separated by $$\sim$$ 18 days. The was in a low flux state during observations, spectra were found to be harder than usual. presence soft excess identified broadband continuum modelled power-law black body (modified intrinsic absorption) distant neutral reflection component. did not find any variability spectral shape or over this period. However, is variable between observations. obtained analysis point scenario where primary emission suppressed component due dominates observed spectrum

FUSE observations of the Blue Compact Dwarf Galaxy Mrk 59
New FUSE far-UV spectroscopy of the nearby metal-deficient (Z⊙/8) cometary Blue Compact Dwarf (BCD) galaxy Markarian (Mrk) 59 is discussed. The data are used to investigate element abundances in its interstellar medium. The H i absorption lines are characterized by narrow cores which are interstellar in origin and by broad wings which are stellar in origin. The mean interstellar H i column dens...
متن کاملThe XMM–Newton view of Mrk 3 and IXO 30
We present the analysis of the XMM-Newton EPIC pn spectrum of the Seyfert 2 galaxy, Mrk 3. We confirm that the source is dominated by a pure Compton reflection component and an iron Kα line, both produced as reflection from a Compton-thick torus, likely responsible also for the large column density (1.36 −0.04 × 10 24 cm) which is pierced by the primary powerlaw only at high energies. A low inc...
متن کاملFlaring from the supermassive black hole in Mrk 335 studied with Swift and NuSTAR
Monitoring of the narrow line Seyfert 1 galaxy Markarian 335 (Mrk 335) with the Swift satellite discovered an X-ray flare beginning 2014 August 29. At the peak, the 0.5-5 keV count rate had increased from that in the low flux state by a factor of 10. A target of opportunity observation was triggered with NuSTAR, catching the decline of the flare on 2014 September 20. We present a joint analysis...
متن کاملDiscovery of high-frequency iron K lags in Ark 564 and Mrk 335
We use archivalXMM-Newton observations of Ark 564 and Mrk 335 to calculate the frequencydependent time lags for these two well-studied sources. We discover high-frequency Fe K lags in both sources, indicating that the red wing of the line precedes the rest-frame energy by roughly 100 and 150 s for Ark 564 and Mrk 335, respectively. Including these two new sources, Fe K reverberation lags have b...
متن کاملA New Superwind Wolf - Rayet Galaxy Mrk 1259
We report the discovery of a starburst-driven wind (superwind) from the starburst nucleus galaxy Mrk 1259. The estimated number ratio of Wolf-Rayet (WR) to O stars amounts to ≃ 0.09. While the nuclear emission-line region is due to usual photoionization by massive stars, the circumnuclear emission-line regions show anomalous line ratios that can be due to cooling shocks. Since the host galaxy s...
