Magnetic field structures in star-forming regions : mid-infrared imaging polarimetry of K3-50
(2015-11-01)We report new imaging polarimetry observations of the Galactic compact H ii region K3-50 using CanariCam at the Gran Telescopio Canarias. We use a standard polarimetric analysis technique, first outlined by Aitken, to ... -
Magnetic Fields in Astrophysical Jets : From Launch to Termination
(2012)Long-lived, stable jets are observed in a wide variety of systems, from protostars, through Galactic compact objects to active galactic nuclei (AGN). Magnetic fields play a central role in launching, accelerating, and ... -
Magnetic fields in discs : what can be learned from infrared and mm polarimetry ?
(2002)Polarimetric imaging in the infrared and submm offers the possibility of identifying magnetic field configurations in astronomical objects. To test this conjecture a set of field geometries within internally heated discs ... -
Magnetic fields in galactic haloes
(2012-05)Magnetic fields on a range of scales play a large role in the ecosystems of galaxies, both in the galactic disk and in the extended layers of gas away from the plane. Observing magnetic field strength, structure and ... -
Magnetic fields in massive star-forming regions
(2007-12-01)We present the largest sample of high-mass star-forming regions observed using sub- millimetre imaging polarimetry. The data were taken using SCUBA in conjunction with the polarimeter on the JCMT in Hawaii. In total, 16 ... -
Magnetic Fields in Star Forming Regions - Near-Infrared and Submillimeter Approaches
(Astronomical Society of the Pacific, 1996)In order to study the magnetic field structure in star forming regions on various scales, we have been conducting both near-infrared and submillimeter polarimetry toward nearby molecular clouds. The near-infrared approach ... -
Magnetic fields in the infrared dark cloud G34.43+0.24
(2019-09-24)We present the B-fields mapped in IRDC G34.43+0.24 using 850\,$\mu$m polarized dust emission observed with the POL-2 instrument at JCMT. We examine the magnetic field geometries and strengths in the northern, central, and ... -
Magnetic Fields toward Ophiuchus-B Derived from SCUBA-2 Polarization Measurements
(2018-07-01)We present the results of dust emission polarization measurements of Ophiuchus-B (Oph-B) carried out using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) camera with its associated polarimeter (POL-2) on the ... -
Magnetic resonance imaging and tensor-based morphometry in the MPTP non-human primate model of Parkinson's disease
(2017-07-24)Parkinson's disease (PD) is the second most common neurodegenerative disorder producing a variety of motor and cognitive deficits with the causes remaining largely unknown. The gradual loss of the nigrostriatal pathway is ... -
Magnetic Resonance Imaging Assessment of Squamous Cell Carcinoma of the Anal Canal Before and After Chemoradiation: Can MRI Predict for Eventual Clinical Outcome?
(2010)Purpose: To describe the MRI appearances of squamous cell carcinoma of the anal canal before and after chemoradiation and to assess whether MRI features predict for clinical outcome. Methods and Materials: Thirty-five ... -
Magnetohydrodynamic stability of broad line region clouds
(2012-10-01)Hydrodynamic stability has been a longstanding issue for the cloud model of the broad line region in active galactic nuclei. We argue that the clouds may be gravitationally bound to the supermassive black hole. If true, ... -
A Magnified View of Circumnuclear Star Formation and Feedback around an Active Galactic Nucleus at z = 2.6
(2018-10-10)We present Atacama Large Millimeter/submillimeter Array observations of an intrinsically radio-bright (L 1.4 GHz = (1.7 ± 0.1) ×10 25 W Hz -1) and infrared luminous (L IR ≈ 10 13 L o) galaxy at z = 2.6. The infrared-to-radio ... -
Magnitude or Direction? Seasonal Variation of Inter-limb Asymmetry in Elite Academy Soccer Players
(2022-04-30)Previous research has highlighted a distinct lack of longitudinal data for asymmetry. The aims of the present study were to provide seasonal variation data for the magnitude and direction of asymmetry. Eighteen elite male ... -
The MAGPI Survey -- science goals, design, observing strategy, early results and theoretical framework
(2021-07-26)We present an overview of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, a Large Program on ESO/VLT. MAGPI is designed to study the physical drivers of galaxy transformation at a lookback ... -
Main sequence of star forming galaxies beyond the Herschel confusion limit
(2018-07-30)Context. Deep far-infrared (FIR) cosmological surveys are known to be affected by source confusion, causing issues when examining the main sequence (MS) of star forming galaxies. In the past this has typically been partially ... -
Mais a Temer do que Esperar: educação radical e classe trabalhadora
(2021-11-10)This article engages with the question of a radical political education from the perspective of a global working class. It explores what form such an education would take and why such an education is central to the creation ... -
Major among the minors: a cultural materialist reading of Julius Caesar
(Routledge, 2006-06-04)When Metellus Cimber makes this contribution at the conspirators’ conference in Brutus’s orchard, he is alerting his fellow confederates to the essential importance of including Cicero in their design to overthrow Caesarean ... -
Major histocompatibility complex I‐induced endoplasmic reticulum stress mediates the secretion of pro‐inflammatory muscle‐derived cytokines
(2022-11-25)Major histocompatibility complex (MHC) I is an important component of intracellular antigen presentation. However, improper expression of MHC I upon the cell surface has been associated with several autoimmune diseases. ... -
Major mergers are not significant drivers of star formation or morphological transformation around the epoch of peak cosmic star formation
(2017-03-01)We investigate the contribution of major mergers (mass ratios > 1 : 5) to stellar mass growth and morphological transformations around the epoch of peak cosmic star formation (z ∼ 2). We visually classify a complete sample ...
