Abstract. We review the on-orbit spectroscopic observations that are being used to characterize the Charge Transfer Efficiency (CTE) of the STIS CCD in spectroscopic mode. We parametrize the...

Abstract. The huge archive of STIS observations constitutes a unique —and arguably the most comprehensive — source of spectroscopy in the UV and spatiallyresolved spectroscopy in the optical...
In the last decade we have come to realize that the traditional classification of stellar clusters into open and globular clusters cannot be easily extended beyond the realm of the Milky Way, and...
Tip of the Red Giant Branch Distances to NGC 4214, UGC 685, and UGC 5456 (2001)
Maíz-Apellániz, Jesús, Cieza, Lucas, MacKenty, John W.
We have used WFPC2 VRI observations to calculate the distances to three nearby galaxies, NGC 4214, UGC 685, and UGC 5456 using the tip of the red giant branch method. Our values for NGC 4214 (2.94...
The origin of the Local Bubble (2001)
The Sun is located in a low-density region of the interstellar medium partially filled with hot gas that is the likely result of several nearby supernova explosions within the last 10 Myr. Here we...
Structural Properties of Massive Young Clusters (2001)
We have retrieved multicolor WFPC2/HST data from the STScI archive for 27 nearby Massive (>= 3x10^4 M_Sun) Young (< 20 Myr) star Clusters (MYCs). The data represents the most-complete-to-date sample...
The spatial distribution of O-B5 stars in the solar neighborhood as measured by Hipparcos (2001)
We have developed a method to calculate the fundamental parameters of the vertical structure of the Galaxy in the solar neighborhood from trigonometric parallaxes alone. The method takes into account...
HST/WFPC2 and VLA Observations of the Ionized Gas in the Dwarf Starburst Galaxy NGC 4214 (2000)
MacKenty, John W., Maíz-Apellániz, Jesús, Pickens, Christopher E., Norman, Colin A., Walborn, Nolan R.
We present new H alpha and [O III] 5007 narrow band images of the starbursting dwarf galaxy NGC 4214, obtained with the WFPC2 onboard HST, together with VLA observations of the same galaxy. The HST...
On the ongoing multiple blowout in NGC 604 (2000)
Tenorio-Tagle, Guillermo, Muñoz-Tuñón, Casiana, Pérez, Enrique, Maíz-Apellániz, Jesús, Medina-Tanco, Gustavo
Several facts regarding the structure of NGC 604 are examined here. The three main cavities, produced by the mechanical energy from massive stars which in NGC 604 are spread over a volume of 10$^6$...
