Supernovae at High Redshift
Distant supernovae provide a convenient tool for cosmology. As bright beacons with small variation in their peak luminosity Type Ia Supernovae can be... -
Nuclear Activity and Galaxy Evolution
This talk discusses the connection between nuclear activity and galaxy evolution. First, the evidence for a fundamental connection is reviewed. Then,... -
Solar Nebulae and Replenished Dust Disks with Planets
Having studied the primordial, protoplanetary gas disks, and older, dusty “remnant” disks in infrared-emitting (Vega-type) circumstellar systems, we... -
Observations of Cygnus X-3 in Quiescence in the $2.4 - 12 \mu$ m Range with ISO
We present mid-infrared spectrophotometric and imaging photometric results obtained with ISO on the peculiar X-ray binary Cygnus X-3. The... -
SINFONI - Galaxy Dynamics at $0^{\prime\prime}\hspace{-0.2cm}.05$ Resolution with the VLT
The SINFONI integral field spectrometer for the VLT will provide nearinfrared spatially resolved spectra at spatial resolutions close to the... -
Discovery of an X-Ray Outburst in an Optically Non-Active Galaxy
The main X-ray and optical properties of a very luminous X-ray outburst source are summarized. The results are: large variability in X-ray emission... -
The CORALIE Planet-Search Sample
This short contribution presents a description of the CORALIE sample selection of more than 1600 dwarf stars for the planet-search programme on the... -
On the Formation of Jets
The phenomenology of jets associated with a variety of black hole systems is summarized, emphasizing the constraints imposed on their origin. Models... -
Modelling Synchrotron Outbursts in 3C 273
We present an improved approach to derive the observed evolution of a typical synchrotron outburst in 3C 273. The method consists in a simultaneous... -
Evidence of a Supernova Origin for the Black Hole in GRO J1655-40 (Nova Scorpii 1994)
We report the discovery of a strong overabundance of several $\alpha$... -
Type Ia Supernovae: Progenitors and Diversities
A key question for supernova cosmology is whether the peak luminosities of Type Ia supernovae (SNe Ia) are sufficiently free from the effects of... -
Evidence for Core Collapse in the Type Ib/c SN 1999ex
We present optical and infrared spectra of SN 1999ex, which are characterized by the lack of strong hydrogen lines, weak optical He I lines, and... -
Freeze-Out Effects in Hydrogen and Helium Lines of SN 1987A at the Early Photospheric Epoch
We have developed a time-dependent model of ionization, excitation and energy balance of the atmosphere of SN 1987A at the photospheric epoch to... -
Circumstellar Interaction Around Supernovae
Circumstellar interaction has been observed around all types of massive star supernovae, especially at radio and X-ray wavelengths. The interaction... -
Light Echoes in Type Ia Supernovae
Light echoes are a promising tool to probe the environment where SNe Ia explode and an independent source of information on the progenitor’s nature.... -
Supernova Signatures in Meteorites
This review focuses on signatures of nucleosynthesis in supernovae that can be traced via isotope abundance anomalies in meteorites. Primary examples... -
Inflection Points on the Light Curves of Type Ia Supernovae
While the distribution of supernova absolute magnitudes at peak is often investigated, there was no systematic study of absolute light curve behavior... -
Simulations of Solar AO Systems
In this paper, first we compare the two kinds of algorithms that are being used in solar AO systems to sense a distorted wave-front through... -
The Nearby Supernova Factory
The Nearby Supernova Factory is an international project dedicated to the study of the nearby thermonuclear (type Ia) supernovæ. Based upon the NEAT... -
Selected Examples of Solar and Extra-Solar Planetary Science with AO
High spatial resolution planetary science has seen a large boost from AO observations complementing space missions. Adaptive optics is particularly...
