Abstract We present a new derivation of the Milky Way’s current star formation rate (SFR) based on data Herschel InfraRed Galactic Plane Survey (Hi-GAL). estimate distribution SFR across plane from star-forming clumps identified in Hi-GAL survey and calculate total sum their contributions. The global amounts to 2.0 ± 0.7 M ⊙ yr −1 , which 1.7 0.6 coming with reliable heliocentric distance assignment. This value is general agreement estimates found literature last decades. profile density...
In Italy, "Telecommunications, Earth Observation, and Navigation" (TLC/EO/NAV) assets are currently exploited to realize services applications (the so-called downstream) providing benefits citizens public institutions, translating space technology investments into significant social economic gains. Among the downstream satellite-based products of most interest for Italian there was support civil protection environmental safeguard from natural anthropogenic hazards.In this context, Space...
We present BeppoSAX follow-up observations of GRB 980425 obtained with the Narrow Field Instruments (NFI) in 1998 April, May, and November. The first NFI observation has detected within 8' radius error box gamma-ray burst (GRB) an X-ray source positionally consistent supernova 1998bw, which exploded a day 980425, fainter source, not position supernova. former is following pointings exhibits decline factor 2 six months. If it associated SN this detection emission from Type I above keV. latter...
We have studied four complex organic molecules (COMs), the oxygen-bearing methyl formate (CH 3 OCHO) and dimethyl ether OCH ) as well nitrogen-bearing formamide (NH 2 CHO) ethyl cyanide (C H 5 CN), towards a large sample of 39 high-mass star-forming regions representing different evolutionary stages, from early to evolved phases. aim identify potential correlations chemical links between trace their sequence through star formation process. analysed spectra obtained at 3, 2, 0.9 mm with...
Stars form preferentially in clusters embedded inside massive molecular clouds, many of which contain high-mass stars. Thus, a comprehensive understanding star formation requires robust and statistically well-constrained characterization the early evolution these clusters. To achieve this, we designed ALMAGAL Large Program that observed 1017 star-forming regions distributed throughout Galaxy, sampling different evolutionary stages environmental conditions. In this work, present acquisition...
A large fraction of stars form in clusters containing high-mass stars, which subsequently influences the local and galaxy-wide environment. Fundamental questions about physics responsible for fragmenting molecular parsec-scale clumps into cores a few thousand astronomical units (au) are still open, that only statistically significant investigation with ALMA is able to address; instance: identification dominant agents determine core demographics, mass, spatial distribution as function...
COSMO-SkyMed (CSK) is the largest Italian investment in Space Systems for Earth Observation, commissioned and funded by Agency (ASI) Ministry of Defense (It-MoD). The CSK constellation has been completely qualified orbit since 2010 it still operating at full performance with a four mid-sized satellites placed Low Orbit, each carrying high-resolution X-band Synthetic Aperture Radar (SAR), full-featured Ground Segment to exploit observation capabilities providing SAR imaging servicing...
COSMO-SkyMed is a Dual-Use (Civilian and Defence) end-to-end Earth Observation System aimed at establishing global service supplying provision of data, products services relevant to wide range applications, such as Risk Management, Scientific Commercial Applications Defence Applications. The system consists constellation four LEO mid-sized satellites, each equipped with multimode high-resolution SAR operating X-band. Three out satellites have been successfully launched, while the remaining...
Spring 2014 signs the beginning of fourth operational year complete Italian four-satellite dualuse system COSMO-SkyMed (COnstellation small Satellites for Mediterranean basin Observation).

The gamma-ray burst (GRB) 980329 is the brightest detected so far with Wide Field Cameras aboard BeppoSAX, in both gamma rays and X-rays. With respect to its fluence (2.6×10−5 ergs s−1 cm−2 50-300 keV), it would be top 4% of bursts 4B catalog (Meegan et al.). time-averaged spectrum from 2 20 keV 70 650 can well described by empirical model Band al. resulting photon index above break energy exceptionally hard at -1.32±0.03. An X-ray afterglow was narrow-field instruments BeppoSAX 7 hr after...
