Persistent nuclear burning in Nova Sgr 2016 N.4 (=V5856 Sgr = ASASSN-16ma) six years past its outburst

U. Munari, Nicola Masetti, F. M. Walter, Robert Edward Williams et autres

We report on the fast Nova Sgr 2016 N.4 being surprisingly trapped in a long-lasting and bright plateau (ΔI≥10 mag above quiescence) six years past the nova eruption. Very few other novae experience a similar occurrence. We carried out an intensive observing …

First detection of the Crab Nebula at TeV energies with a Cherenkov telescope in a dual-mirror Schwarzschild-Couder configuration: the ASTRI-Horn telescope

Saverio Lombardi, O. Catalano, Salvatore Scuderi, Lucio Angelo Antonelli et autres

We report on the first detection of very high-energy gamma-ray emission from the Crab Nebula by a Cherenkov telescope in dual-mirror Schwarzschild-Couder (SC) configuration. This result has been achieved by means of the 4m ASTRI-Horn telescope, operated on Mt. Etna, Italy, and …

Photometric evolution of seven recent novae and the double-component characterizing the light curve of those emitting in gamma rays

U. Munari, Franz-Josef Hambsch, A. Frigo

The BVI light curves of seven recent novae (i.e. V1534 Sco, V1535 Sco, V2949 Oph, V3661 Oph, MASTER OT J010603.18–744715.8, TCP J1734475–240942 and ASASSN-16ma) have been extensively mapped with daily robotic observations from Atacama (Chile): five belong to the Galactic bulge, one …

Photometric evolution of the 2016 outburst of recurrent Nova LMC 1968: the first three weeks

U. Munari, F. M. Walter, F.-J. Hambsch, A. Frigo

Optical (BVRI) photometry of the first three weeks of the 2016 outburst of the recurrent Nova LMC 1968 is presented and discussed. The 2016 I-band light-curve is an exact replica, even in the most minute details, of that for the 2010 eruption. …
