Kinematics of the HH 111 jet from STIS spectra
A. C. Raga, A. Noriega-Crespo, B. Reipurth +4
We present a long-slit spectrum of the Herbig-Haro object HH 111, obtained with SITS on the Hubble Space Telescope. This spectrum has a spectral resolution of approx. 50 km/s, so i…
The Optical Proper Motions of HH 7-11 and Cep E (HH 377)
Alberto Noriega-Crespo, Peter M. Garnavich
A key ingredient in understanding the dynamics of stellar outflows is their proper motion. We have used optical images in the [SII] emission at 6717/31 A and the red Digitized Palo…
The Discovery of Cepheids and a New Distance to NGC 2841 Using the Hubble Space Telescope
L. M. Macri, P. B. Stetson, G. D. Bothun +5
We report on the discovery of Cepheids in the spiral galaxy NGC 2841, based on observations made with the Wide Field and Planetary Camera 2 on board the Hubble Space Telescope. NGC…
The Luminosity of SN 1999by in NGC 2841 and the Nature of `Peculiar' Type Ia Supernovae
Peter M. Garnavich, Alceste Z. Bonanos, Kevin Krisciunas +9
We present UBVRIJHK photometry and optical spectroscopy of the so-called 'peculiar' Type Ia supernova 1999by in NGC 2841. The observations began one week before visual maximum ligh…
Rapid UBVRI Follow-up of the Highly Collimated Optical Afterglow of GRB010222
K. Z. Stanek, P. M. Garnavich, S. Jha +6
(Abridged) We present the earliest optical observations of the optical counterpart to the GRB 010222, obtained with the FLWO 1.2-m telescope in UBVRI passbands, starting 3.64 hours…
Complete and Simultaneous Spectral Observations of the Black-Hole X-ray Nova XTE J1118+480
J. E. McClintock, C. A. Haswell, M. R. Garcia +13
The X-ray nova XTE J1118+480 suffers minimal extinction (b = 62 degrees) and therefore represents an outstanding opportunity for multiwavelength studies. Hynes et al. (2000) conduc…
