Performance of the image persistence model for Euclid infrared detectors Open
Large-format infrared detectors are at the heart of major ground and space-based astronomical instruments, and the HgCdTe HxRG is the most widely used. The Near Infrared Spectrometer and Photometer (NISP) of the ESA’s Euclid mission launch…

Easy remote observations using web interfaces: controlling an Italian telescope from Japan, and more Open
Remote observations are often limited by user interfaces, which seem frozen to another computer era: low performances, outdated programming languages, command-line scripting, high version-dependent software. Instead, web-based tools are st…

Euclid commissioning results: the near infrared spectrometer and photometer (NISP) signal detection chain Open
Euclid, the M2 mission of the ESA’s Cosmic Vision 2015-2025 program, aims to explore the Dark Universe by conducting a survey of approximately 14 000 deg2 and creating a 3D map of the observable Universe of around 1.5 billion galaxies up t…

“Astronomy for sailors”: a web game to learn physics using the stars and a clock Open
If you were on a boat in the middle of the sea how could you guess your position using just the stars and a clock? This is the challenge for hundreds of students at our interactive astronomy workshop in the context of the Genoa Science Fes…

Polyphase tectonics on Mars: Insight from the Claritas Fossae Open
The Claritas Fossae (CF) is an elongated system of scarps and depressions >900 km long, representing the western boundary of the Thaumasia Region to the south of the Tharsis volcanic province. Although there is general agreement on the tec…

The Claritas Fossae region, an example of polyphasic deformation on Mars? Open
<p>The Claritas Fossae (CF) is a Martian system of scarps and troughs with NNE-SSE elongation that exceeds 1000 km of length and 150 km of width. It develops mainly in Late to Middle Noachian highland units and Hesperian lava flows (…

Toward the remotization and robotization of the OARPAF telescope Open
OARPAF (Osservatorio Astronomico Regionale Parco Antola Comune di Fascia, Italy) hosts an 80cm Astelco telescope with a Gambato Dome, SBIG-STX camera, Davis weather station, and SBIG AllSky camera. We present a layer-structured python3 fra…

CAPS: A New Method for the Identification of Different Surface Displacements in Landslide and Subsidence Environments through Correlation Analysis on Persistent Scatterers Time-Series from PSI Open
Persistent Scatterer Interferometry (PSI) is one of the most powerful tools for identifying and monitoring areas exposed to surface deformations such as landslides or subsidence. In this work, we propose a new method that we named CAPS (Co…

Time-delay estimation in unresolved lensed quasars Open
Time-delay cosmography can be used to infer the Hubble parameter H0 by measuring the relative time delays between multiple images of gravitationally lensed quasars. A few of such systems have already been used to measure H0: Their time del…

Modelling the extensional tectonic setting of the Claritas Fossae Open
<p>Unravelling the tectonic styles that affected the Martian crust is crucial to better understand the evolutionary stages that a rocky planet can experience. Here, we explore the tectonic setting of a key region of Mars, namely the …

Persistent Scatterer Interferometry and Statistical Analysis of Time-Series for Landslide Monitoring: Application to Santo Stefano d’Aveto (Liguria, NW Italy) Open
Landslides are a major threat for population and urban areas. Persistent Scatterer Interferometry (PSI) is a powerful tool for identifying landslides and monitoring their evolution over long periods and has proven to be very useful especia…

Analysis of tectonic structures on the Martian surface: a contribution to the understanding of the crustal dichotomy Open
The Martian crustal dichotomy is the main physiographic feature at planetary scale on Mars and marks the topographic and geological boundary between the northern Lowlands and the southern Highlands. It can be easily followed over the entir…

Cerberus: A three-headed instrument for the OARPAF telescope Open
We present the preliminary design of Cerberus, a new scientific instrument for the alt-az, 80cm OARPAF telescope in the Ligurian mountains above Genoa, Italy. Cerberus will provide three focal stations at the Nasmyth focus, allowing: imagi…

High response photochromic films based on D–A diarylethenes and their application in holography Open
Photochromic diarylethenes with D–A structure are good candidates in holography thanks to their very large modulation of the complex refractive index.

Analysis of the Angular Dependence of Time Delay in Gravitational Lensing Open
We consider an alternative formula for time delay in gravitational lensing. Imposing a smoothness condition on the gravitationally deformed paths followed by the photons from the source to the observer, we show that our formula displays th…
