An HST/NICMOS view of the prototypical giant HII region NGC604 in M33
Rodolfo H. Barba, Jesus Maiz Apellaniz, Enrique Perez +5
We present the first high-spatial resolution near-infrared (NIR) imaging of NGC 604, obtained with the NICMOS camera aboard the Hubble Space Telescope (HST). These NICMOS broadband…
Fractal dimension of interstellar clouds: opacity and noise effects
Nestor Sanchez, Emilio J. Alfaro, Enrique Perez
There exists observational evidence that the interstellar medium has a fractal structure in a wide range of spatial scales. The measurement of the fractal dimension (Df) of interst…
On emission-line spectra obtained from evolutionary synthesis models I. Dispersion in the ionising flux and Lowest Luminosity Limits
M. Cervino, V. Luridiana, E. Perez +2
(abriged) Stellar clusters with the same general physical properties (e.g., total mass, age, and star-formation mode) may have very different stellar mass spectra due to the incomp…
Multiwavelength observations of short time-scale variability in NGC 4151. I. Ultraviolet observations
D. M. Crenshaw et al
We present the results of an intensive ultraviolet monitoring campaign on the Seyfert 1 galaxy NGC 4151, as part of an effort to study its short time-scale variability over a broad…
