The radial profiles of five spiral galaxies (NGC 5194, NGC 3627, NGC 3351, NGC 5055, NGC 4736) in the J and K filters of the near infrared are presented. They were taken with the 1.5 m Carlos Sanchez Telescope of the Observatorio del Teide (Tenerife). The infrared photometric parameters of the disk and bulge of NGC 5194 (M51), are calculated. The

Recent Spitzer Space Telescope observations of several astrophysical environments such as planetary nebulae, reflection nebulae and R Coronae Borealis stars show the simultaneous presence of mid-infrared features attributed to neutral fullerene molecules (i.e. C60) and polycyclic aromatic hydrocarbons (PAHs). If C60 fullerenes and PAHs coexist in

The 4-m aperture Advanced Technology Solar Telescope (ATST) is the next generation ground based solar telescope. In this paper we provide an overview of the ATST post-focus instrumentation. The majority of ATST instrumentation is located in an instrument Coude lab facility, where a rotating platform provides image de-rotation. A high order adaptive

We present single-dish 12CO(1-0) and 12CO(2-1) observations for 14 low-redshift quasi-stellar objects (QSOs). In combination with optical integral field spectroscopy, we study how the cold gas content relates to the star formation rate (SFR) and black hole accretion rate. 12CO(1-0) is detected in 8 of 14 targets and 12CO(2-1) is detected in 7 out

2D-FIS, a bundle of 125 optical fibres mounted in the focal plane of the WHT, has been used to study two-dimensional stellar kinematics and populations in nearby galaxies.

Integral-field spectroscopy (IFS) has merited much attention in recent years due to its advantages with respect to classical sequential 2-D spectroscopic techniques (e.g., long-slit scans, Fabry-Perot) when studying relatively small extended objects. IFS is able to simultaneously obtain a spectrum for each spatial sample of a two-dimensional field.
