    Abstract Euclid is an medium-class ESA mission that will carry out a 5 year survey of the extragalactic sky. The science drivers for the survey are cosmological and extragalactic. Nevertheless, the unprecedented depth over such a large area and the diffraction limited spatial resolution of the Euclid survey will have a long lasting impact in many fields of Astrophysics. This paper outlines the legacy science that will come out from Euclid in the field of ultracool dwarfs. In particular, it is foreseen that Euclid will increase the number of resolved ultracool binaries by more than an order of magnitude, and hence it will provide a stringent constraint on models of formation of very low-mass objects. Euclid can also find significant number of rare objects such as young free-floating planets or population III ultracool dwarfs.

    Abstract We discuss the possibility of using the transmission spectrum of the Earth in the measurements of the molecules abundance ratios. We use optical and near infrared transmission spectrum of the Earth obtained during observations of a lunar eclipse in 2008 by Enric Palle and others (E. Pallé et al., 2009). This task is interesting in terms of estimation of the chemical composition of the Earth-like planets around other stars during their transits. We use one-slab model approach for modelling transmission spectra using HITRAN line database. Comparison with observational data gives us clues to our problem.

    Abstract We compare Smoothed Particle Hydrodynamic simulations of retrogradely precessing accretion disks that have a white dwarf primary and a main sequence secondary with observational data and with theory on retrograde precession via tidal torques like those by the Moon and the Sun on the Earth [1, 2]. Assuming the primary does not accrete much of the mass lost from the secondary, we identify the theoretical low mass star/brown dwarf boundary. We find no observational candidates in our study that could qualify as brown dwarfs.

    Abstract High-resolution spectroscopy in the near-infrared could become the leading method for discovering extra-solar planets around very low-mass stars and brown dwarfs. To help to achieve an accuracy of about 1 m/s, we are developing a gas cell which consists of a mixture of gases whose absorption spectral lines span all over the near-infrared region. We here present a summary of the working technique and the main results obtained so far.

    Abstract The form and universality of the mass function of young and nearby star-forming regions is still under debate. Its relation to the stellar density, its mass peak and the dependency on most recent models shows significant differencies for the various regions and remains unclear up to date. We aim to get a more complete census of two of such regions. We investigate yet unexplored areas of Orion and Taurus-Auriga, observed by the UKIDSS survey. In the latter, we search for low-mass stars via photometric and proper motion criteria and signs for variability. In Orion, we search for small stellar clumps via nearest-neighbor methods. Highlights in Taurus would be the finding of the missing low-mass stars and the detection of a young cluster T dwarf. In Orion, we discovered small stellar associations of its OB1b and OB1c populations. Combined with what is known in literature, we will provide by this investigations a general picture of the results of the star-forming processes in large areas of Taurus and Orion and probe the most recent models.

    Abstract We present an approach to improve the radial velocity precision of NIRSPEC data (spectral resolution R = λ/Δλ ≈ 22,000) by using a self-calibration approach. We demonstrate that the accuracy can be significantly improved by deconvolving the spectra and using the telluric lines as a long-term stable wavelength reference.

    Abstract With excellent energy resolution and ultralow-level radiogenic backgrounds, the high-purity germanium detectors in the Majorana Demonstrator enable searches for several classes of exotic dark matter (DM) models. In this work, we report new experimental limits on keV-scale sterile neutrino DM via the transition magnetic moment from conversion to active neutrinos ν_{s}→ν_{a}. We report new limits on fermionic dark matter absorption (χ+A→ν+A) and sub-GeV DM-nucleus 3→2 scattering (χ+χ+A→ϕ+A), and new exclusion limits for bosonic dark matter (axionlike particles and dark photons). These searches utilize the (1-100)-keV low-energy region of a 37.5-kg y exposure collected by the Demonstrator between May 2016 and November 2019 using a set of ^{76}Ge-enriched detectors whose surface exposure time was carefully controlled, resulting in extremely low levels of cosmogenic activation.

    Abstract Primary graft failure (PGF) is one of the major complications that occurs immediately following lung transplantation and greatly contributes to increased morbidity and mortality. The incidence of PGF is correlated with a marked decline in endogenous nitric oxide (NO) and cyclic guanosine monophosphate (cGMP) levels. Therefore, the administration of NO during lung transplantation has been proposed as a possible therapeutic treatment to prevent or attenuate PGF pathogenesis. Despite the initial positive results of experimental and uncontrolled clinical trials, recent randomized clinical trials do not support the prophylactic administration of inhaled nitric oxide (iNO) for the prevention of PGF following lung transplantation under the conditions tested. Nonetheless, there is evidence that iNO administration during PGF can improve oxygenation and reduce pulmonary hypertension without altering systemic vascular resistance. This suggests that iNO may prevent the need for extracorporeal membrane oxygenation (ECMO) during the hypoxic phase of PGF. During the intraoperative phase of transplantation, one-lung ventilation (OLV) and pulmonary artery clamping usually increase PVR, causing decreased right ventricular function and hemodynamic instability. The administration of iNO during these lung transplant procedures could decrease right ventricular dysfunction by reducing PVR and help to avoid the use of cardiopulmonary bypass.
