Gaia, an ESA cornerstone mission, will obtain of the order of 100 high-precision photometric observations over five years for tens of millions of stars with V ...
Transmission Spectroscopy of HAT-P-32Ab with GTC/OSIRIS
I will present one of the latest results of our GTC exoplanet transit spectroscopy survey. Over the last years our group has obtained ground-based optical (538...
Transmission- to Reflection-dominated Transition in Seyfert 2 Galaxies: the XMM-Newton View
In this paper we present the current status of a XMM-Newton program to observe an optically-defined, complete and unbiased sample of Compton-thick Seyfert 2...
Transport, handling, and integration of the adaptive optics system for GTC: from the laboratory to the telescope
The Gran Telescopio de Canarias Adaptive Optics System (GTCAO) is currently in its commissioning phase at Roque de Los Muchachos Observatory (ORM). The GTCAO is...
Transportable ground station for QKD using adaptive optics
This article summarizes the results of a system engineering approach to the design of a Transportable Optical Ground Station (TOGS) intended to be used for...
Transportable optical ground station for QKD using adaptive optics with a plenoptic wavefront sensor
The Institute of Astrophysics of the Canary Islands, IAC, and specifically its technology transfer division IACTEC, has a long history of participation in free...
During last years, direct evidence about oscillations in different coronal structures has been obtained thanks to the detailed observations made by SoHO and...
The surface-brightness profiles of galaxy disks fall into three main classes, based on whether they are simple exponentials (Type I), bend down at large radii...
Triaxiality can Explain the Alleged Dark Matter Deficiency in some Dwarf Galaxies
Dark Matter (DM) is an ingredient essential to the current cosmological concordance model. It provides the gravitational pull needed for the baryons to form...
