Título/Title: The Gemini Multi Object Spectrograph (GMOS)
Resumo/Abstract:
|
This seminar will discuss the principal characteristics of
the GMOS and a science case: GMOS Observations of Strong
Gravitational-Lensing features in Abell 3827 (z~0.1). The Gemini Multi Object spectrograph is one of the most
used instrument at Gemini. An optimal use of this facility instrument
requires a better knowledgement of its capabilities (observing modes,
reductions techniques using the gmos package). The two days seminar will be
divided as follow: Wednesday 14th: during the first hour I will review the
main characteristics of the instrument and will show the discovering of
features due to strong gravitational lensing of background sources near the
center of the cluster Abell 3827 (z~0.1) based on GMOS-S observations obtained
in 2007B semester. The second hour will be devoted to GMOS data
format and GMOS data reduction techniques, including the brief
introduction to the Gemini Mask Making Software. |
