Multi-band behaviour of the TeV blazar PG 1553+113 in optical range on diverse timescales
A. Agarwal, B. Mihov, I. Andruchow +11
Context. The TeV BL Lac object PG 1553+113 is one of the primary candidates for a binary supermassive black hole system. Aims. We study the flux and spectral variability of PG 1553…
Discovery of thermonuclear (Type I) X-ray bursts in the X-ray binary Swift J1858.6-0814 observed with NICER and NuSTAR
D. J. K. Buisson, D. Altamirano, P. Bult +22
Swift J1858.6-0814 is a recently discovered X-ray binary notable for extremely strong variability (by factors in soft X-rays) in its discovery state. We present the detectio…
Soft X-ray emission lines in the X-ray binary Swift J1858.6-0814 observed with XMM-Newton-RGS: disc atmosphere or wind?
D. J. K. Buisson, D. Altamirano, M. Díaz Trigo +11
We find soft X-ray emission lines from the X-ray binary Swift J1858.6-0814 in data from XMM-Newton-RGS: N VII, O VII and O VIII, as well as notable residuals short of a detection a…
Infrared-detected AGNs in the Local Universe
Tuba İkiz, Reynier F. Peletier, Peter D. Barthel +1
Spitzer/IRAC color selection is a promising technique to identify hot accreting nuclei, that is to say AGN, in galaxies. We demonstrate this using a small sample of SAURON galaxies…
The variable radio counterpart of Swift J1858.6-0814
J. van den Eijnden, N. Degenaar, T. D. Russell +18
Swift J1858.6-0814 is a transient neutron star X-ray binary discovered in October 2018. Multi-wavelength follow-up observations across the electromagnetic spectrum revealed many in…
The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation
J. L. Ortiz, P. Santos-Sanz, B. Sicardy +90
Among the four known transneptunian dwarf planets, Haumea is an exotic, very elongated, and fast rotating body. In contrast to the other dwarf planets, its size, shape, albedo, and…
