Pixel simulations are essential in serval phases of a project as they provide mock data that allows us to design, test and optimize the analysis of the images, prior to the real observations. They are also key to evaluate the performance of a survey and help understanding the causes of unknown systematics once the mission starts.

In this talk I will explain the work I (with many others) have done in producing pixel image simulations for various cosmology surveys such as DES, DESI, PAU and Euclid. For the Dark Energy Survey Camera (DECam) and the Dark Energy Spectroscopy Instrument (DESI) were we are responsible of the auto-guiding system we simulated realistic detector images. Secondly, I will present the PAUCam-WHT pixel simulations, used to design the data reduction pipeline. And finally I will give an overview of the Euclid science ground segment and explain the work at the Organization Unit of SIM, detailing all the end-to-end simulations we are currently delivering for the mission.

X-MRIs and IMRIs - From extremely large to intermediate

The gravitational capture of a compact object by a supermassive black hole is the best probe of strong gravity we have thought of.
I will present recent results that predict that such gravitational captures can be detected in the future with space-borne detectors
right at our Galactic Centre with extreme signal-to-noise ratios and extremely large mass ratios, via the capture of sub-stellar objects.
Also, I will show that it is likely that current ground-based detectors such as LIGO and Virgo already have buried in their data
captures of intermediate-mass ratios.

THE 1908 TUNGUSKA EVENT: 111 YEARS AFTER, IT STILL MAKES YOU THINK


Start: 12:15h
Speaker: Luigi Foschini (INAF - Brera)
Place: Alberto Lobo

On June 30th, 1908, an explosion flattened more than two thousands square kilometres of Siberian taigà. During the following 111 years, several theories were proposed to explain the observed features. Basically, there is a general agreement on the collision of the Earth with a cosmic body, but still…

On June 30th, 1908, an explosion flattened more than two thousands square kilometres of Siberian taigà. During the following 111 years, several theories were proposed to explain the observed features. Basically, there is a general agreement on the collision of the Earth with a cosmic body, but still today there are doubts on the exact dynamics of the phenomenon and the nature of the body (comet or asteroid?). Particularly, I will address the atmospheric fragmentation and the possibility of a ground impact.
