We report the first detection of an optical millisecond pulsar with fast photon counter Aqueye+ in Asiago. This is independent confirmation pulsations from PSR J1023+0038 obtained SiFAP at Telescopio Nazionale Galileo. observed transitional mounted Copernicus telescope January 2018. Highly significant were detected. The rotational period agreement value extrapolated X-ray ephemeris, while time passage ascending node shifted by $11.55 \pm 0.08$ s predicted using orbital X-rays. An timing...
The Vela pulsar is among a number of pulsars which show detectable optical pulsations. We performed observations this in 2009 January and December with the Iqueye instrument mounted at ESO 3.5 m New Technology Telescope. Our aim was to perform phase fitting data, measure pulse profile high time resolution, its absolute phase, rotational period. calculated for first an independent timing solution obtained most detailed available date. detected distinct narrow component on top one two main...
We present a timing analysis of the transitional millisecond pulsar PSR J1023+0038 using observations taken between January 2018 and 2020 with high time resolution photon counter Aqueye+ mounted at 1.82 m Copernicus telescope in Asiago. report first measurement solution frequency derivative based entirely on optical data. The spin-down rate is $(-2.53 \pm 0.04) \times 10^{-15}$ Hz$^2$, which $\sim$20% slower than that measured from X-ray 2013-2016 $\sim$5% faster radio band during...
Our team at the INAF-Astronomical Observatory of Padova and University is engaged in design, construction operations instruments with very high time accuracy optical band for applications to High Time Resolution Astrophysics Quantum Astronomy. Two were built perform photon counting sub-nanosecond temporal accuracy, Aqueye+ Iqueye. regularly mounted 1.8m Copernicus telescope Asiago, while Iqueye was several 4m class telescopes around world now attached through Fiber Interface 1.2m Galileo...
Fast sub-second optical variability exists in some important classes of astrophysical sources, particular pulsars and X-ray binaries.We regularly perform ultra-fast photometric campaigns on the most interesting targets transient events.At same time, we are tackling new searching for fast other types sources (Fast Radio Bursts, magnetars).To this end use develop dedicated photon counting instrumentation visible band, an area which our team is leader.Observations carried out within framework...
Stellar intensity interferometry (SII) is based on the correlation of light fluctuations a star detected at two or more telescopes, with no need to combine collected photons directly. A measurement in full "photon-counting mode" was experimented fast photon counters Italy (2016-2020) and currently being adapted ASTRI Mini-Array. Performing image synthesis "photon-counting" SII requires series preparatory activities that involve optimization pipelines for treatment time acquired extremely...
The ASTRI Stellar Intensity Interferometry Instrument (SI3) is a fast single photon counting instrument for performing intensity interferometry observations of bright stars with the Mini-Array. SI3 designed to perform accurate measurements arrival times (1ns) in narrow optical bandwidth (1-8nm) centered at wavelength range 420-500nm. will exploit 36 simultaneous baselines over distances between 100m and 700m Mini-Array achieve angular resolutions below 100 microarcsec. At this level...
Several types of Galactic sources, like magnetars, microquasars, novae or pulsar wind nebulae flares, display transient emission in the X-ray band. Some these sources have also shown at MeV--GeV energies. However, none transients ever been detected very-high-energy (VHE; E$>$100 GeV) regime by any Imaging Air Cherenkov Telescope (IACT). The Transient task force is a part Working group Array (CTA) Consortium. investigates prospects detecting VHE counterpart such as well their study following...
