The Aligned z~1 Radio Galaxy 3C 280

DOI: 10.1086/379660 Bibcode: 2004ApJ...600...70R

Lacy, Mark; Stockton, Alan; Ridgway, Susan E.

The z~1 radio galaxy 3C 280 has a particularly striking rest-frame UV morphology, with multiple line and continuum components precisely aligned with the radio structure, including an obvious semicircular arc. Here we explore the nature of these various components by bringing together Hubble Space Telescope and ground-based imaging, ground-based sp…

Detailed SUMER Observations of Coronal Loop Footpoint Dynamics

DOI: 10.1086/381776 Bibcode: 2004ApJ...604..449M

McIntosh, Scott W.; Poland, Arthur I.

For the most part, the characteristics of heating in the open corona and in closed coronal loops are determined by observing the emitted plasma intensity as a function of position and comparing this with model calculations. There are also some efforts that include observed velocity and still others that use theoretical physical processes such as e…

Shock-cloud interactions in the Vela SNR: preliminary results of an XMM-Newton observation

DOI: 10.1016/j.asr.2003.08.016 Bibcode: 2004AdSpR..33..381B

Miceli, M.; Bocchino, F.; Maggio, A.

The study of the clumpy and irregular features in the X-ray emission of middle-aged supernova remnants shells allows us to shed light on the various characteristic of the interstellar medium, like its structure and composition. We have observed with XMM-Newton a small knot in the Vela SNR, which previous ROSAT studies have indicated as one of the …

Sporadic plasma streams and their sources in the period of extraordinary solar activity from October 26 to November 6, 2003

DOI: 10.1007/s10604-005-0004-x Bibcode: 2004CosRe..42..571E

Eselevich, M. V.; Eselevich, V. G.

Based on the results of investigations made by various authors applying different semiempirical models, we have formulated the principles of a complex method that allows one to associate sporadic streams of the solar wind (SW) at the Earth’s orbit with coronal mass ejections (CMEs), which are their sources on the Sun. This method is applied to an …

Measurements of brightness and nonradial direction of coronal streamers according to data of SOHO/Large Angle and Spectrometric Coronagraph Experiment (LASCO)-C2

DOI: 10.1029/2004GI000069 Bibcode: 2004IJGA....5.2011K

Tlatov, A. G.; Kim, Gun-Der; Makarov, V. I.

Daily observations of the corona were processed according to the data of coronagraph SOHO/Large Angle and Spectrometric Coronagraph Experiment (LASCO)-C2 to study the variations of brightness and nonradial direction of coronal streamers during 1996.5-2003.5. Photometry of coronal images was carried out at heights of $2.3~R_\odot-5.5~R_{\…

Numerical simulation of the visible and near infrared radiance of Mars: effects of atmospheric scattering

DOI: 10.1016/j.asr.2003.07.075 Bibcode: 2004AdSpR..34.1683B

Erard, S.; Blecka, M. I.

This paper presents new simulations of the radiance of the surface and atmosphere of Mars. Our modeling is directly connected with future spectrometric measurements of two instruments on Mars Express (short-wavelength channel of PFS and OMEGA) and of the VIRTIS spectrometer on-board Rosetta which was planned for observation of Mars in August 2005.…

Optimal Galaxy Shape Measurements for Weak Lensing Applications Using the Hubble Space Telescope Advanced Camera for Surveys

DOI: 10.1086/379697 Bibcode: 2004ApJ...600L.159P

Ferguson, Henry C.; Casertano, Stefano; Park, Yousin

We present three-epoch multiband (V₆₀₆, i₇₇₅, and z₈₅₀) measurements of galaxy shapes using the ``polar shapelet'' or Laguerre expansions method with the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) data, obtained as part of the Great Observatories Origin Deep Survey (GOODS). We take advantage of …

The circumstellar environment of the star V923 Aquilae

DOI: 10.1051/0004-6361:20034435 Bibcode: 2004A&A...417..679A

Ringuelet, A. E.; Arias, M. L.; Cidale, L. S.

V923 Aquilae is a Be shell star that displays emission in Hα, cyclic V/R variations and variations in the intensity of the near infrared continuum. The star presents radial velocity variations arising from a superposition of a long-term cycle and an orbital motion with a period of 214.756 days (Koubský et al. \cite{koub}). To in…

Flickering Red Giants in the Ursa Minor Dwarf Spheroidal Galaxy: Detection of Low-Amplitude Variability in Faint Red Giant Branch Stars on 10 Minute Timescales

DOI: 10.1086/426965 Bibcode: 2004ApJ...617L..41M

Roederer, Ian U.; Mighell, Kenneth J.

We have analyzed two epochs of Hubble Space Telescope Wide Field Planetary Camera 2 observations of the Ursa Minor dwarf spheroidal galaxy using the HSTphot photometric reduction package. We report the detection of nine faint (M_V>~0.0 mag) red giant variable stars that exhibit low-amplitude brightness fluctuations on 10 minute timesc…
