H3 Line Survey Towards the Galactic Center
The H3 in the interstellar medium is a unique probe of physical and chemical environments in dense and diffuse clouds. As the observational study in many lines of sight is becoming matured, we have as many problems newly found. The overabundance of H3 in diffuse clouds is one of them [3, 4]. We undertook the absorption line survey of H3 toward the Galactic center sources to shed light on it [1]...
متن کاملTiming measurements and proper motions of 74 pulsars using the Nanshan radio telescope
We have measured the positions of 74 pulsars from regular timing observations using the Nanshan radio telescope at Urumqi Observatory between 2000 January and 2004 August (MJD 51500 – 53240). Proper motions were determined for these pulsars by comparing their current positions with positions given in pulsar catalogues. We compare our results to earlier measurements in the literature and show th...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
HST Pa Survey of the Galactic Center – Searching the missing young stellar populations within the Galactic Center
We present preliminary results of our HST Paα survey of the Galactic Center (GC), which maps the central 0.65×0.25 degrees around Sgr A*. This survey provides us with a more complete inventory of massive stars within the GC, compared to previous observations. We find 157 Paα emitting sources, which are evolved massive stars. Half of them are located outside of three young massive star clusters ...
