We present detections of emission at 250 GHz (1.2 mm) from two high-redshift QSOs from the Sloan Digital Sky Survey sample using the bolometer array at the IRAM 30 m telescope. The sources are SDSSp 015048.83+004126.2 at z=3.7 and SDSSp J03...

Observations of the damped Lyalpha systems provide direct measurements on the chemical enrichment history of neutral gas in the early universe. In this Letter, we present new measurements for four damped Lyalpha systems at high redshift. Co...

The formation rate of luminous galaxies seems to be roughly constant from z approximately 2 to approximately 4 from the recent observations of Lyman break galaxies (LBGs). The abundance of luminous quasars, on the other hand, appears to dro...
Heliospheric X-ray Emission Associated with Charge Transfer of the Solar Wind with Interstellar Neutrals [0.03%]

X-rays should be generated throughout the heliosphere as a consequence of charge transfer collisions between heavy (Z>2) solar wind ions and interstellar neutrals. The high charge state solar wind ions resulting from these collisions are le...

Observations obtained with the Midcourse Space Experiment (MSX) satellite reveal for the first time the complex mid-infrared morphology of the entire Carina Nebula (NGC 3372). On the largest size scale of approximately 100 pc, the thermal i...
Detection of Extended Thermal Infrared Emission around the Vega-like Source HD 141569 [0.03%]

We report the detection of extended IR emission at 10.8 and 18.2 µm around the Vega-like source HD 141569. Mid-IR imaging with OSCIR on Keck II shows emission from dust extending out to 100 AU from the B9.5 Ve star. Our modeling of the dus...

We analyze the wind generated by the great 20 yr-long super-Eddington outburst of eta Carinae. We show that by using the classical stellar atmosphere and wind theory, it is impossible to construct a consistent wind model in which a sufficie...
