Title: | High-energy monitoring of Seyfert galaxies: The case of NGC 4593 | Authors: | Ursini, Francesco Petrucci, P. -O. Matt, G. BIANCHI, STEFANO CAPPI, MASSIMO De Marco, B. DE ROSA, ALESSANDRA Malzac, J. PONTI, GABRIELE |
Issue Date: | 2016 | Journal: | ASTRONOMISCHE NACHRICHTEN | Number: | 337 | First Page: | 552 | Abstract: | We discuss preliminary results from a joint XMM-Newton and NuSTAR monitoring program on the active galactic nucleus NGC 4593, consisting of 5 × 20 ks observations, spaced by two days, performed in January 2015. The source is found to be variable, both in flux and spectral shape, on time scales as short as a few ks. The spectrum clearly softens when the source brightens. A simple timing analysis suggests the presence of a variable soft excess that correlates with the primary continuum. | URI: | http://hdl.handle.net/20.500.12386/30520 | URL: | http://arxiv.org/abs/1510.01966v1 https://onlinelibrary.wiley.com/doi/abs/10.1002/asna.201612346 |
