The CVN technology of this file allows you to export and import curricular data from and to any compatible data base. List of adapted databases available at: http://cvn.fecyt.es/ 4154b7e2be6a86b67f637261e4ad3d11 General quality indicators of scientific research This section describes briefly the main quality indicators of scientific production (periods of research activity, experience in supervising doctoral theses, total citations, articles in journals of the first quartile, H index...). It also includes other important aspects or peculiarities. My name is Javier Peralta and I was born in Algeciras (1979, Spain). I graduated in Physics at the University of La Laguna (Spain) in 2003, specializing in the fields of Astrophysics and Applied Physics. In 2009, I got an European PhD degree in Physics at the University of the Basque Country (Spain) with the highest qualification ("Cum Laude") . My PhD research, supervised by Professors Agustín Sánchez-Lavega and Ricardo Hueso, focused on the atmospheric dynamics of the planet Venus using data from the space missions Galileo and Venus Express. As a result, 6 articles were published in international peer review journals (4 of them as first author) along with more than 80 citations which allowed to be awarded in 2012 with the “Extraordinary Prize of Doctorate” granted by the University of the Basque Country. After my PhD, I spent the last 10 years (2009-2019) working in different research institutions as postdoctoral researcher: 2 years at IAA/CSIC in Granada (Spain), 3 years at the Astronomical Observatory of Lisbon (CAAUL/OAL, Portugal) and 5 years at the Institute of Space and Astronautical Science of Japan (ISAS/JAXA), funded by JAXA's International Top Young Fellowship (ITYF). -

However, several big challenges remain, many of which could be addressed using machine learning methodology. For instance, the most prolific method for detecting exoplanets and inferring several of their characteristics, transit photometry, is very sensitive to the presence of stellar spots. The current practice in the literature is to identify the effects of spots visually and correct for them manually or discard the affected data. -

What Is CHEOPS?
Swiss and ESA satellite CHEOPS launching soon! CHEOPS will be launching into space on the 17th of December! You may be wondering: what is CHEOPS? CHEOPS stands for CHaracterising ExOPlanet Satellite. Its goal is to study transits of already-known exoplanets to gain more knowledge about them. What type of information are we looking for? Scientists want to know detailed information about planets outside our Solar System, such as the mass, planet size, and density, which will in turn help to figure out the composition of these exoplanets. Studying exoplanet composition and their atmospheres is important especially for astrobiology. A planet’s chemical composition can affect its habitability for life as we know it. Scientists usually look for biosignatures such as the presence of methane or oxygen in the planet’s atmosphere, which could indicate presence of past or present life. Artist’s impression of CHEOPS. Credits: ESA / ATG medialab. The major contributors CHEOPS is a collaboration between ESA and the Swiss Space Office. The mission was proposed and is now headed by Prof. Willy Benz, from the University of Bern, which houses the mission’s consortium. The science operations consortium is at the University of Geneva, where they have many collaborators, such as the Swiss Space Center at EPFL. As it is an ESA endeavour, many other European institutions are also contributing to the mission. For example, the mission operations consortium is located in Torrejón de Ardoz, Spain. The launch The satellite has already been shipped to Kourou, French Guiana, where it will be launched by the ESA spaceport. -

RIT Faculty Part of NASA's $242M Spherex Mission
6/10/2021 RIT faculty part of NASA’s $242M SPHEREx mission | RIT Rochester Institute of Technology February , by Luke Auburn Follow @lukeauburn RIT faculty part of NASA’s $M SPHEREx mission Michael Zemcov on the team that will explore the origins of the universe, galaxies and water in planetary systems Caltech NASA’s Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission is targeted to launch in . SPHEREx will help astronomers understand both how our universe evolved and how common are the ingredients for life in our galaxy’s planetary systems. A Rochester Institute of Technology professor is part of a small team of scientists contributing to NASA’s new mission to explore the origins of the universe by performing the first near-infrared all-sky spectral survey. Assistant Professor Michael Zemcov is one of co-investigators of the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) mission, which received $ million in funding from NASA today. SPHEREx has three primary objectives. First, SPHEREx will map galaxies across much of the universe to study inflation, the rapid expansion thought to play a part in the universe’s creation. The mission also seeks to gain new insights into the origin and history of galaxy formation by measuring spatial fluctuations in the extragalactic background light. Third, SPHEREx aims to answer questions about the amount and evolution of key biogenic molecules such as water and carbon monoxide throughout all phases of star and planetary formation. “I’m very excited by the opportunity to help explain if and how inflation happened, and to understand more about it,” said Zemcov. -

A Polarized View of the Hot and Violent Universe
A Polarized View of the Hot and Violent Universe A White Paper for the Voyage 2050 long-term plan in the ESA Science Programme Contact Scientist: Paolo Soffitta (INAF - Istituto di Astrofisica e Planetologia Spaziali, via Fosso del Cavaliere 100, 00133 Roma, Italy; [email protected]) INTRODUCTION Since the birth of X-ray Astronomy, spectacular advances have been seen in the imaging, spectroscopic and timing studies of the hot and violent X-ray Universe, and further leaps forward are expected in the future with the launch e.g. in early 2030s of the ESA L2 mission Athena. A technique, however, is very much lagging behind: polarimetry. In fact, after the measurement, at 2.6 and 5.2 keV, of the 19% average polarization of the Crab Nebula and a tight upper limit of about 1% to the accreting neutron star Scorpius X-1 (not surprisingly, the two brightest X-ray sources in the sky), obtained by OSO-8 in the 70s, no more observations have been performed in the classical X-ray band, even if some interesting results have been obtained in hard X-rays by balloon flights like POGO+ (Chauvin et al., 2017, 2018a,b, 2019) and X-Calibur (Kislat et al., 2018, Krawczynski et al., in prep.), and in soft gamma-rays by INTEGRAL (Forot et al., 2008, Laurent et al., 2011, Gotz et al., 2014), Hitomi (Aharonian et al., 2018) and AstroSAT (Wadawale et al. 2017). The lack of polarimetric measurements implies that we are missing vital physical and geometrical information on many sources which can be provided by the two additional quantities polarimetry can provide: the polarization degree, which is related to the level of asymmetry in the systems (not only in the distribution of the emitting matter, but also in the magnetic or gravitational field), and the polarization angle, which indicates the main orientation of the system. -

We aim to determine far-infrared fluxes at 70, 100, and 160 µm for the five major Uranus satellites, Titania, Oberon, Umbriel, Ariel, and Miranda. Our study is based on the available calibration observations at wavelengths taken with the PACS photometer aboard the Herschel Space Observatory. Methods. The bright image of Uranus was subtracted using a scaled Uranus point spread function (PSF) reference established from all maps of each wavelength in an iterative process removing the superimposed moons. The photometry of the satellites was performed using PSF photometry. Thermophysical models of the icy moons were fitted to the photometry of each measurement epoch and auxiliary data at shorter wavelengths. Results. The best-fit thermophysical models provide constraints for important properties of the moons, such as surface roughness and thermal inertia.
