Near Infrared Imaging Polarimetry of Proto-Planetary Nebula - OH231.8+4.2
(Astronomical Society of the Pacific, 2002) -
Near Infrared Polarimetry of IRAS 19306+1407
(Astronomical Society of the Pacific, 2005)Polarimetry can be used to observe the dusty outer shells of Post- AGB stars. We can discriminate between the unpolarized light from the central star and the re°ected polarized °ux. The polarisation vectors and polarized ... -
Near infrared spectroscopic search for the close orbiting planet HD 75289b
(2007)We present a search for the near infrared spectroscopic signature of the close orbiting extrasolar giant planet HD 75289b. We obtained »230 spectra in the wavelength range 2.18 ¹m- 2.19 ¹m using the Phoenix spectrograph ... -
Near-Capacity Sphere Decoder Based Detection Schemes for MIMO Wireless Communication Systems
(University of Hertfordshire, 2013-07-08)The search for the closest lattice point arises in many communication problems, and is known to be NP-hard. The Maximum Likelihood (ML) Detector is the optimal detector which yields an optimal solution to this problem, but ... -
Near-death experiences : exploring the mind-body connection
(Routledge, 2008)Near death experiences fascinate everyone, from theologians to sociologists and neuroscientists. This groundbreaking book introduces the phenomenon of NDEs, their personal impact and the dominant scientific explanations. ... -
Near-death states reported in a sample of 50 misusers
(2010)Increase in recreational ketamine use may be a cause for concern. We aimed here at assessing, in a sample of ketamine misusers, concordance between the typical near-death experience (NDE) features and the on-drug psychoactive ... -
Near-Field Terahertz Communications: Model-Based and Model-Free Channel Estimation
(2023-04-11)Terahertz (THz) band is expected to be one of the key enabling technologies of the sixth generation (6G) wireless networks because of its abundant available bandwidth and very narrow beamwidth. Due to high frequency ... -
Near-infrared and millimetre polarimetry of CEN A
(1996)We present near-infrared polarization images of the nuclear region of CenA, and millimetre polarimetry of the nucleus. In the near-infrared the polarization vectors mainly lie along the dust lane, with the polarization ... -
Near-infrared circular polarimetry and correlation diagrams in the Orion Becklin-Neugebauer/Kleinman-low region: contribution of dichroic extinction
(2009)We present a deep circular polarization (CP) image of the Orion Becklin-Neugebauer (BN)/Kleinman-Low (KL)nebula in the K-s band and correlations of CP, linear polarization (LP) and H-K-s color representing extinction. The ... -
Near-infrared Circular Polarization Images of NGC 6334-V
(2013-03-01)We present results from deep imaging linear and circular polarimetry of the massive star-forming region NGC 6334-V. These observations show high degrees of circular polarization (CP), as much as 22% in the Ks band, in the ... -
Near-infrared circular polarization survey in star-forming regions : Correlations and trends
(2014-11-01)We have conducted a systematic near-infrared circular polarization (CP) survey in star-forming regions, covering high-mass, intermediate-mass, and low-mass young stellar objects. All the observations were made using the ... -
Near-infrared high imaging polarimetry of the Red Rectangle
(2003)We have carried out KHL band high resolution imaging and H band imaging-polarimetry of the Red Rectangle nebula using CIAO and 36 element AO mounted on the 8.2m Subaru telescope. HK band images show a X-shape structure ... -
Near-infrared imaging observations of the southern massive star-forming region G333.6-0.2
(2005)We present near-infrared broad-band JHK' images of the southern massive star-forming region G333.6−0.2. The slope of the K-luminosity function towards the region (0.24 ± 0.01) is considered to be equivalent to that expected ... -
Near-infrared imaging polarimetry of bipolar nebulae 1:the BN-KL region of OMC-1
(1991)New high-spatial-resolution polarization images of the BN-KL region of OMC-1 from 1.25-3.6 microns are presented. At the longer wavelengths these show a centro-symmetric polarization vector pattern, centered mainly on IRc2, ...
