The complete set of data from the Tenerife 10-GHz (8-deg FWHM) twin-horn, drift scan experiment is described. These data are affected by both long-term...
Recent studies of warp kinematics using Gaia DR2 data have produced detections of warp precession for the first time, which greatly exceeds theoretical...
According to the latest cosmological models, large spiral galaxies such as the Milky Way grew by absorbing smaller galaxies, by a sort of galactic cannibalism...
Just as archaeology examines the ground with great care to find valuable objects which helps us to get to know ancient civilizations, astronomers look at the...
Preliminary results are presented from a spectroscopy survey of IRAS sources with colors similar to those of planetary nebulae. Two new planetary nebulae, some...
Via optical low-resolution long slit spectroscopy conducted at the 2.5 m INT in La Palma, He, O, N, Ne, A, and S abundances in 13 extended PN were calculated...
Galaxy formation by gravitational instability implies the presence of temperature fluctuations in the cosmic microwave background. New observations at 10.45 and...
Scientists from the Instituto de Astrofísica de Canarias (IAC), in collaboration with the University of Cambridge and the University of California San Diego...
We present maps of the stellar streams detected in the Gaia Data Release 2 (DR2) and Early Data Release 3 (EDR3) catalogs using the STREAMFINDER algorithm. We...
