Photogrammetric Processing of Planetary Linear Pushbroom Images Based on Approximate Orthophotos
Geng, X.; Xu, Q.; Xing, S. +3 more
It is still a great challenging task to efficiently produce planetary mapping products from orbital remote sensing images. There are many disadvantages in photogrammetric processing of planetary stereo images, such as lacking ground control information and informative features. Among which, image matching is the most difficult job in planetary pho…

Análisis temporal y espectral en rayos X de la fuente IGR J16320-4751
Chaty, S.; García, F.; Fogantini, F. +1 more
We present the results obtained from an in depth timing and spectral analysis of IGR J16320-4751, a High Mass X-ray binary system comprised of a neutron star orbiting and accreting matter from the stellar wind of its supergiant companion. From a total of nine XMM-Newton observations, we computed and analyzed the time evolution of physical paramete…
Lunar and Planetary Geology
Basilevsky, Alexander T.
Lunar and planetary geology can be described using examples such as the geology of Earth (as the reference case) and geologies of the Earth's satellite the Moon; the planets Mercury, Mars and Venus; the satellite of Saturn Enceladus; the small stony asteroid Eros; and the nucleus of the comet 67P Churyumov-Gerasimenko. Each body considered is illu…
Is HH 47 Slowing Down?
Velázquez, P. F.; Raga, A. C.; Noriega-Crespo, A.
We have used three epochs of red [S II] and Hα Hubble Space Telescope (HST) archival images of HH 47 to determine the proper motion velocities of the knots along the jet. With the three available epochs we compute two sets of proper motions (one using the first two epochs, and the second one using the last two epochs). Somewhat surprisingly, we fi…
Billion-star map of Milky Way set to transform astronomy
Castelvecchi, Davide
European Gaia spacecraft's first major data dump — the most detailed 3D chart yet of our Galaxy — will keep researchers busy for decades.

An analytical approach to the CMB polarization in a spatially closed background
Niazy, Pedram; Abbassi, Amir H.
The scalar mode polarization of the cosmic microwave background is derived in a spatially closed universe from the Boltzmann equation using the line of sight integral method. The EE and TE multipole coefficients have been extracted analytically by considering some tolerable approximations such as considering the evolution of perturbation hydrodyna…
