The central kpc of the Milky Way might be expected to differ significantly from rest Galaxy with regard gasdynamics and formation young stellar objects (YSOs). We probe this possibility mid-infrared observations obtained Infrared Array Camera Multiband Imaging Photometer on Spitzer Midcourse Space Experiment. use color–color diagrams spectral energy distribution (SED) fits explore nature YSO candidates (including 4.5 μm excesses possibly due molecular emission). There is an asymmetry in...
We present a catalog of 9017 X-ray sources identified in Chandra observations 2°× 08 field around the Galactic center. This enlarges number known region by factor 2.5. The incorporates all ACIS-I as 2007 August, which total 2.25 Ms exposure. At distance to center (8 kpc), we are sensitive with luminosities 4 × 1032 erg s−1 (0.5–8.0 keV; 90% confidence) over an area 1 deg2, and up order magnitude more deepest exposure (1.0 Ms) Sgr A*. positions 60% our accurate <1 '' (95% confidence), 20%...
Our HST/NICMOS Pa survey of the Galactic center (GC) provides a uniform, panoramic, high-resolution map stars and ionized diffuse gas in central 416 arcmin^2 Galaxy. This was carried out with 144 HST orbits using two narrow-band filters at 1.87 1.90 micron NICMOS Camera 3. In this paper, we describe detail data reduction mosaicking procedures followed, including background level matching astrometric corrections. We have detected ~570,000 near-IR sources are able to quantify photometric...
Abstract In this introduction, we propose the notion of ‘embodied belonging’ as a fruitful analytical heuristic for scholars in medical and psychological anthropology. We envision to help us gain more nuanced understanding entanglements political, social, affective dimensions belonging their effects on health, illness, healing. A focus embodied belonging, argue, reveals how displacement, exclusion, marginalization cause existential health-related ruptures people’s lives bodies, affected...
We have recently carried out the first wide-field hydrogen Paschen-alpha line imaging survey of Galactic Center (GC), using NICMOS instrument aboard Hubble Space Telescope. The maps a region 2253 pc^2 around central supermassive black hole (Sgr A*) in 1.87 and 1.90 Micron narrow bands with spatial resolution 0.01 pc at distance 8 kpc. Here we present an overview observations, data reduction, preliminary results, potential scientific implications, as well description rationale design survey....
ABSTRACT We report the discovery of 19 hot, evolved, massive stars near Galactic center region (GCR). These objects were selected for spectroscopy owing to their detection as strong sources Paschen-α (Pα) emission-line excess, following a narrowband imaging survey central 0.°65 × 0.°25 ( l , b ) around Sgr A* with Hubble Space Telescope . Discoveries include six carbon-type (WC) and five nitrogen-type (WN) Wolf–Rayet stars, O supergiants, two B supergiants. Two supergiants have X-ray...
We present new observations of the quiescent giant molecular cloud GCM0.253+0.016 in Galactic center, using upgraded Karl G. Jansky Very Large Array. Observations were made at wavelengths near 1 cm, K (24 to 26 GHz) and Ka (27 36 bands, with velocity resolutions 1-3 km/s spatial ~0.1 pc, assumed 8.4 kpc distance this cloud. The continuum are most sensitive yet made, reveal previously undetected emission which we attribute primarily free-free from external ionization In addition map, produce...
ABSTRACT Increasing droughts adversely affect grasslands, diminishing the availability and quality of forages for ruminants. We have recently shown that mixed ensiling drought‐impaired grass (DIG) with sugar beet pulp (SBP) improved conservation feed value silage. The application silage additives may further improve ruminal degradability, which thereby shape fermentation microbiome in rumen when those silages are tested as part dairy diets. Therefore, we performed a long‐term vitro...
The Arches cluster is an extraordinarily compact massive star with a core radius of about 10'' (~0.4 pc) and consisting more than 150 O candidates initial stellar masses greater 20 M☉ near G0.12-0.02. X-ray observations the radio Arc Galactic center at l ~ 02, which contains cluster, have been carried out Advanced CCD Imaging Spectrometer (ACIS) on board Chandra X-Ray Observatory. We report detection two sources from embedded within bath diffuse emission extending beyond edge to least 90'' ×...
We report on the discovery of an apparent triple radio structure hidden inside bubble ultraluminous X-ray source Holmberg II X-1. The morphology is consistent with a collimated jet structure, which observed to emit optically thin synchrotron radiation. central component has steep spectrum and brighter than outer components indicating renewed activity. estimate minimum time-averaged power 2 x 10^{39} erg/s that associated isotropic luminosity at least 4 erg/s. Our results suggest X-1 powered...
There is a limited research focus on evaluating the detrimental effects of prolonged zearalenone (ZEN) intake dairy cows’ health under controlled conditions. This experiment was conducted to evaluate whether length exposure ZEN-contaminated total mixed ration (TMR) at level 9.45 mg per day can negatively influence animal parameters, such as milk composition, rumen and fecal fermentation, chewing activity lactating cows. For this experiment, we used 18 Simmental cows that were fed diet 60%...
We present new extinction maps and high-resolution Paschen alpha images of G-0.02-0.07, a complex compact HII regions located adjacent to the M-0.02-0.07 giant molecular cloud, 6 parsecs in projection from center Galaxy. These regions, which lie just outside boundary Sgr A East supernova remnant, represent one most recent episodes star formation central The 1.87 micron extinctions A, B C are almost identical, approximately 1.5 magnitudes. Region D, contrast, has peak 2.3 Adopting Nishiyama...
ABSTRACT The Snake is a remarkable Galactic Centre radio filament with morphology characterized by two kinks along its ∼20 arcmin extent. major and minor are located where the most distorted from linear magnetized structure running perpendicular to plane. We present Chandra, VLA, MeerKAT data report detection of an X-ray source at location kink. High-resolution images kink reveal compact steep spectrum spectral index α ∼ −2.7 surrounded extended emission. luminosity consistent pulsar. also...
We report on the discovery of a luminous blue variable (LBV) lying ≈7 pc in projection from Quintuplet cluster. This source, which we call LBV G0.120 − 0.048, was selected for spectroscopy owing to its detection as strong source Paschen-α (Pα) excess recent narrowband imaging survey Galactic center region with Hubble Space Telescope/Near-Infrared Camera and Multi-Object Spectrometer.

Abstract Observed dysphoric (chronically but not clinically depressed) mothers with their infants from 3 months following birth to the preschool stage (M = 3.9 years). The of had lower interaction ratings and heart rate variability. At stage, dyads also ratings, rated children as being more vulnerable having internalizing (depressed) externalizing problems (aggressive destructive). Only at age were significantly related infancy measures, including Profile Mood States (mothers' depressed...
We report the detection of two elongated X-ray features, G359.89-0.08 and G359.54+0.18, in Galactic center (GC) region using Chandra X-Ray Observatory. is an feature located ∼2' projection south Galaxy, Sgr A*.
