Digging Into the Surface of the Icy Dwarf Planet Eris
M. R. Abernathy, S. C. Tegler, W. M. Grundy +4
We describe optical spectroscopic observations of the icy dwarf planet Eris with the 6.5 meter MMT telescope and the Red Channel Spectrograph. We report a correlation, that is at t…
Visible spectroscopy in the neighborhood of 2003 EL61
N. Pinilla-Alonso, J. Licandro, V. Lorenzi
Context: The recent discovery of a group of trans-neptunian objects (TNOs) in a narrow region of the orbital parameter space and with surfaces composed of almost pure water ice, be…
Study of the Surface of 2003 EL61: the largest carbon-depleted object in the trans-neptunian belt
N. Pinilla-ALonso, R. Brunetto, J. Licandro +3
2003 EL61 is the largest member of a group of TNOs with similar orbits and 'unique' spectra (neutral slope in the visible and the deepest water ice absorption bands ever observed i…
The dark nature of GRB 051022 and its host galaxy
A. J. Castro-Tirado, M. Bremer, S. McBreen +17
We present multiwavelength (X-ray/optical/near-infrared/millimetre) observations of GRB 051022 between 2.5 hours and ~1.15 yr after the event. It is the most intense gamma-ray burs…
The water ice rich surface of (145453) 2005 RR43: a case for a carbon-depleted population of TNOs?
N. Pinilla-Alonso, J. Licandro, R. Gil-Hutton +1
Recent results suggest that there is a group of TNOs (2003 EL61 being the biggest member), with surfaces composed of almost pure water ice and with very similar orbital elements. W…
Comet 162P/Siding Spring: A Surprisingly Large Nucleus
Y. R. Fernandez, H. Campins, M. Kassis +5
We present an analysis of thermal emission from comet 162P/Siding Spring (P/2004 TU12) measured during its discovery apparition in 2004 December. The comet showed no dust coma at t…
Visible spectroscopy of 2003 UB313: Evidence for N2 ice on the surface of the largest TNO?
J. Licandro, W. M. Grundy, N. Pinilla-Alonso +1
The recent discovery of two large trans-Neptunian objects (TNOs) 2003 UB313 and 2005 FY9, with surface properties similar to those of Pluto, provides an exciting new laboratory for…
Transmission curves and effective refraction indices of MKO near infrared consortium filters at cryogenic temperatures
F. Ghinassi, J. Licandro, E. Oliva +5
We report transmission measurements at cryogenic temperatures for 4 broad-band filters of the Mauna Kea Observatories (MKO) near-infrared filter set and 5 narrow-band filters. The…
NICS-TNG low-resolution 0.85-2.45um spectra of L-Dwarfs: a near-infrared spectral classification scheme for faint dwarfs
L. Testi, F. D'Antona, F. Ghinassi +8
We present complete near-infrared (0.85-2.45 um), low-resolution (~100) spectra of a sample of 26 disk L-dwarfs with reliable optical spectral type classification. The observations…
NICS-TNG infrared spectroscopy of NGC1068: the first extragalactic measurement of [PII] and a new tool to constrain the origin of [FeII] line emission in galaxies
E. Oliva, A. Marconi, R. Maiolino +19
We report 0.9-1.4 micron spectroscopic observations of NGC1068 collected during the commissioning phase of the near infrared camera spectrometer (NICS) of the Telescopio Nazionale…
BVRI photometry of QSO 0957+561A, B: Observations, new reduction method and time delay
M. Serra-Ricart, A. Oscoz, T. Sanchis +5
CCD observations of the gravitational lens system Q0957+561A,B in the BVRI bands are presented in this paper. The observations, taken with the 82 cm IAC-80 telescope, at Teide Obse…
