TWO-FREQUENCY CROSS-SLOT ANTENNA WITH RESONANT COLD ELECTRON BOLOMETERS FOR APPLICATION IN CORE SPACE MISSION
Published 2017-06-01“…As a result of the modeling, the radiation diagram of the antenna in two frequency channels as well as its frequency characteristics are obtained.The calculation gives the following characteristics of the receiving system on the basis of cross-slot antenna: width of the main beam of the radiation diagram – 24.3° and 19.5°, the ellipticity of the beam – 4.2 % and 0.3 %, the bandwidth – 14.9 GHz and 19.0 GHz, polarization resolution – 23.4 dB and 29.6 dB, where the former value refers to the 75 GHz channel, and the latter refers to 105 GHz channel.It is proposed to use a cross-slot antenna in dual-frequency mode together with resonant cold-electron bolometers to work in the receiving system of the orbital telescope COrE. …”

Excess Ultraviolet Emission at High Galactic Latitudes: A New Horizons View
Published 2025-01-01“…The former is the first firm detection of the offset in the range 912–1100 Å while the latter result confirms previous results from the Galaxy Evolution Explorer, showing that there is little emission from the solar system from 1400 to 1800 Å. …”

Chasing the Beginning of Reionization in the JWST Era
Published 2025-01-01“…We consider a model that ends too early ( z _end ≈ 8) alongside two more realistic scenarios with z _end ≈ 5: one starting late ( z ~ 9) and another early ( z ~ 13). We find that the latter requires up to an order-of-magnitude evolution in galaxy ionizing properties at 6 < z < 12, perhaps in tension with measurements of ξ _ion by JWST, which indicate little evolution. …”

ALGUNAS APLICACIONES RECIENTES DE LA TÉCNICA DE RADIO OCULTAMIENTO SATELITAL EN EL ESTUDIO DE PROCESOS ATMOSFÉRICOS
Published 2013-12-01“…In the last years, the use of radio occultation (RO) technique to observe the terrestrial atmosphere and the climate takes advantage of the occultation of the Sun, the Moon, the stars and principally of artificial satellites of low height (LEO). In the latter case, crossed signs between LEO and GPS satellites are used. …”
