The NICMOS team has devised a comprehensive program of observations of the Galactic Center. ... Data in hand give a first look at variability and a detailed look at the search for the tip of the main sequence will be discussed where NICMOS has demonstrated adequate sensitivity and photometric precision to identify likely O8-B1 stars at the Galactic Center. ...

It is difficult to unambiguously match the star with a 2MASS catalog object. ... The variable is the brighter southern star. It was not possible to measure the stars separately using UVOT U and W1 images, so the light curves and the variability amplitudes in these two bands refer to the combination of two stars. ...

... 5 National Astronomy and Ionosphere Center, Cornell University, Ithaca, NY 14853, U.S.A. In this paper we present new radio and near-infrared observations of a bright Halpha knot located south-east of the Cepheus OB3 association, near the ionization front that divides the S155 diffuse HII region from the Cepheus B molecular cloud. ... The larger of the small--diameter components is a blister-type compact HII region, still partly bounded by high density molecular gas. ...

... We intend to use the restored HST to study age structure and chemical evolution of the stellar population at the center of the LMC. ... To study the reduction techniques needed, a set of simulated PC images have been made. ... Two of the generally available photometric software packages, ROMAFOT and DAOPHOT, have been used to analyse the images. Results show that the photometric accuracy reached with these packages is not enough for high precision photometry in this configuration. ...

We are exploring the evolution of massive binary star populations for a nuclear starburst occuring in the conditions similar to the Milky Way galaxy, in its central part, on a time scale of 10 Myr. ... Our results include the number of X-ray transients (NS + main sequence star), super-accreting black holes (BHs), and binaries consisting of a BH + supergiant, all as functions of time. ...

... For this paper: postscript PPEUC CMB index 1 Introduction.. ... We report on a 16 ks X-ray observation with the ROSAT PSPC towards the center of a CMB decrement detected by Jones et al. (1997) in the direction of the quasar pair PC1643+4631 A & B. At the position of the decrement we find no evidence for emission by hot gas which could give rise to the Sunyaev-Zel'dovich effect. ... We conclude that the CMB decrement is not a typical galaxy cluster. ... 2 The ROSAT PSPC observation . ...

... Abstract: We present a search for a low-mass Standard Model Higgs boson produced in association with a z boson decaying to charged leptons at a center-of-mass energy of s\sqrt{s}=1.96~TeV with the D0 detector at the Fermilab Tevatron collider. The search is performed in a large data set of events containing two opposite-sign leptons (electron, muon) and one or two b-tagged jets. 4:00pm, 472 Willamette Hall . ...
