Context. Globular clusters are representative of the oldest stellar populations. It is thus essential to have a complete census of these systems in dwarf galaxies, from which more massive galaxies are progressively formed in the hierarchical scenario. Aims. We present the results of spectroscopic observations of eight globular cluster candidates in NGC 147, a satellite dwarf elliptical galaxy o...

We present high-resolution spectra (R ∼ 3 km s −1) of the interstellar Na  and Ca  interstellar absorption lines observed towards 3 early-type stars with distances of 360 to 1380pc along the line-of-sight towards the 800pc distant Shajn 147 (S147) Supernova Remnant (SNR). These data are supplemented with far-UV (912-1180Å) aborption spectra of HD 36 665 and HD 37 318 recorded with the NASA F...

The supernova remnant S 147 harbors the pulsar PSR J 0538+2817 whose characteristic age is more than an order of magnitude greater than the kinematic age of the system (inferred from the angular offset of the pulsar from the geometric center of the supernova remnant and the pulsar proper motion). To reconcile this discrepancy we propose that PSR J 0538+2817 could be the stellar remnant of the f...

We present VLBA polarimetric observations of the steep-spectrum quasar 3C 147 (0538+498) made at four frequencies in the available 5-GHz band, from which we derived milliarcsecond-resolution images of the total intensity, polarization, and rotation measure distributions. The jet extending to the southwest is followed out to a distance of about 200 mas from the core. The jet shows several gentle...

ObjectiveTo compare the live birth rate between patients who undergo personalized embryo transfer (pET) after endometrial receptivity array (ERA) versus frozen (FET) with standard timing in first single euploid FET cycles. To report of displacement window implantation (WOI) an infertile population without a history failure.DesignProspective cohort study underwent their programmed FET.SettingPri...

147 patients (147 eyes) with age-related cataracts were studied. The density of the lens on Pentacam system was determined for all patients. We compared power applied force ultrasound and equivalent time its use five degrees density. study proved that PentacamHR's shampflug camera is a fairly accurate method determining before surgery, main advantage which non-contact.
