(Taylor and Francis, 2017)Recoverable mineral resources assessment has become a standard geostatistical application in the mining industry, with various geostatistical techniques currently available. This investigation aimed to improve the prediction ...
-
(Oxford University Press, 2018)© 2018 The Author(s). Blazars are known for their energetic multiwavelength flares from radio wavelengths to highenergy γ -rays. In thiswork, we study radio, optical, and γ -ray light curves of 145 bright blazars spanning ...
-
(WILEY-BLACKWELL, 2012-08)We present Swift Ultra-Violet Optical Telescope and X-Ray Telescope (XRT) observations, and visual wavelength spectroscopy of the Type IIb supernova (SN) 2009mg, discovered in the Sb galaxy ESO 121-G26. The observational ...
-
(EDP SCIENCES, 2016)Context. In protoplanetary disks micron-size dust grains coagulate to form larger structures with complex shapes and compositions. The coagulation process changes the absorption and scattering properties of particles in ...
-
(Oxford University Press, 2014)We present Spitzer, near-IR (NIR) and millimetre observations of the massive star-forming regions W5-east, S235, S252, S254-S258 and NGC 7538. Spitzer data is combined with NIR observations to identify and classify the ...
-
(EDP Sciences, 2019)Context. The star formation process requires the dust and gas present in the Milky Way to self-assemble into dense reservoirs of neutral material where the new generation of stars will emerge. Star-forming regions are ...
-
(2007-12-21)We present optical and infrared broad-band images, radio maps, and optical spectroscopy for the nuclear region of a sample of nearby galaxies. The galaxies have been drawn from a complete volume-limited sample for which ...
-
(ESO, 2009)Aims. This work aims at investigating the molecular and infrared components in the massive young stellar object (MYSO) candidate IRAS 18544+0112. The purpose is to determine the nature and the origin of this infrared ...
-
(UNIV CHICAGO PRESS, 2006-01)We present UBVRIz' optical images taken with MOSAIC on the CTIO 4 m telescope of the 0.32 deg(2) Extended Hubble Deep Field-South. This is one of four fields comprising the MUSYC survey, which is optimized for the study ...
-
(UNIV CHICAGO PRESS, 2008-07-10)We present K-band imaging of two similar to 30' x 30' fields covered by the Multiwavelength Survey by Yale-Chile (MUSYC) Wide NIR Survey. The SDSS 1030+05 and Cast 1255 fields were imaged with the Infrared Side Port Imager ...
-
(IOP, 2022)We present the results of variability power spectral density (PSD) analysis using multiwavelength radio to GeV gamma-ray light curves covering timescales of decades/years to days/minutes for the blazars 3C 279 and PKS ...
-
(EDP Sciences, 2020)Context. We report the discovery of TOI 263.01 (TIC 120916706), a transiting substellar object (R = 0.87 R-Jup) orbiting a faint M3.5 V dwarf (V = 18.97) on a 0.56 d orbit.Aims. We setout to determine the nature of the ...
-
(BMJ Publishing Group, 2019)© Author(s) (or their employer(s)) 2019.Background and objective Oculopharyngeal muscular dystrophy (OPMD) is a genetic disorder caused by an abnormal expansion of GCN triplets within the PABPN1 gene. Previous descriptions ...
-
(IOP Publishing, 2016)We present Multi Unit Spectroscopic Explorer (MUSE) integral field spectroscopic observations of the host galaxy (PGC 043234) of one of the closest (z = 0.0206, D similar or equal to 90 Mpc) and best-studied tidal disruption ...
