Hubble Space Telescope/NICMOS Observations of Massive Stellar Clusters near the Galactic Center
We report Hubble Space Telescope (HST) Near-Infrared Camera and Multiobject Spectrometer (NICMOS) observations of the Arches and Quintuplet clusters, two extraordinary young clusters near theExpand

Massive Stars in the Quintuplet Cluster
We present near-infrared photometry and K-band spectra of newly identified massive stars in the Quintuplet cluster, one of the three massive clusters projected within 50 pc of the Galactic center. WeExpand

Massive Stars in the Arches Cluster
We present and use new spectra and narrowband images, along with previously published broadband images, of stars in the Arches cluster to extract photometry, astrometry, equivalent width, andExpand

A Radio Polarimetric Study of the Galactic Center Threads
The Very Large Array has been used to carry out a multifrequency, polarimetric study of the non-thermal filaments (NTF’s), G0.08+0.15, and G359.96+0.09, also known as the Northern and SouthernExpand

Kinematic and structural analysis of the Minispiral in the Galactic Center from BEAR spectro-imagery
Integral field spectroscopy of the inner region of the Galactic Center, over a field of roughly 40 �� ×40 �� was obtained at 2.06 µ m( He) and 2.16 µ m( Brγ) using BEAR, an imaging Fourier TransformExpand

Large, highly organized radio structures near the galactic centre
A radio map of the galactic centre made at a wavelength of 20 cm with the Very Large Array telescope reveals that most of the radio emission arising within 50 pc of the galactic centre is notExpand

AN EXTENDED STAR FORMATION HISTORY FOR THE GALACTIC CENTER FROM HUBBLE SPACE TELESCOPE NICMOS OBSERVATIONS
We present Hubble Space Telescope (HST) Near-Infrared Camera and Multiobject Spectrometer (NICMOS) observations as evidence that continuous star formation has created much of the central stellar cuspExpand

Sustained star formation in the central stellar cluster of the Milky Way
THE central stellar bulge of our Galaxy is commonly thought to consist predominantly of a coeval population of very old (˜1010yr) stars1–3. But evidence for young4 and intermediate-age stars5,6 inExpand

A New Mid-Infrared Map of the BN/KL Region Using the Keck Telescope
We present a new mid-infrared (12.5 μm) map of the BN/KL high-mass star-forming complex in Orion using the LWS instrument on Keck I. Despite poor weather we achieved nearly diffraction-limited imagesExpand
