A New Solution to the Plasma Starved Event Horizon Magnetosphere: Application to the Forked Jet in M87
(2018-06-22)
Very Long Baseline Interferometry observations at 86 GHz reveal an almost hollow jet in M87 with a forked morphology. The detailed analysis presented here indicates that the spectral luminosity of the central spine of the ...
Red, redder, reddest : SCUBA-2 imaging of colour-selected Herschel sources
(2018-06-11)
High-redshift, luminous, dusty star-forming galaxies (DSFGs) constrain the extremity of galaxy formation theories. The most extreme are discovered through follow-up on candidates in large area surveys. Here, we present ...
Low-mass eclipsing binaries in the WFCAM Transit Survey : The persistence of the M-dwarf radius inflation problem
(2018-06-01)
We present the characterization of five new short-period low-mass eclipsing binaries (LMEBs) from the WFCAM Transit Survey. The analysis was performed by using the photometric WFCAM J-mag data and additional low- and ...
The X-ray Ribs Within the Cocoon Shock of Cygnus A
(2018-06-01)
We use new and archival Chandra observations of Cygnus A, totalling ~1.9Ms, to investigate the distribution and temperature structure of gas lying within the projected extent of the cocoon shock and exhibiting a rib-like ...
LeMMINGs – I. The eMERLIN legacy survey of nearby galaxies. 1.5-GHz parsec-scale radio structures and cores
(2018-05-21)
We present the first data release of high-resolution (≤0.2 arcsec) 1.5-GHz radio images of 103 nearby galaxies from the Palomar sample, observed with the eMERLIN array, as part of the LeMMINGs survey. This sample includes ...
Dust attenuation in 2<z<3 star-forming galaxies from deep ALMA observations of the Hubble Ultra Deep Field
(2018-05-21)
We present the results of a new study of the relationship between infrared excess (IRX ≡ L IR/L UV), ultraviolet (UV) spectral slope (β) and stellar mass at redshifts 2 < z < 3, based on a deep Atacama Large Millimeter ...
Revolutionizing Our Understanding of AGN Feedback and its Importance to Galaxy Evolution in the Era of the Next Generation Very Large Array
(2018-05-18)
Energetic feedback by active galactic nuclei (AGNs) plays an important evolutionary role in the regulation of star formation on galactic scales. However, the effects of this feedback as a function of redshift and galaxy ...
The dust and [CII] morphologies of redshift ~4.5 sub-millimeter galaxies at ~200pc resolution : The Absence of Large Clumps in the Interstellar Medium at High-redshift
(2018-05-17)
We present deep, high-resolution (0.″03, 200 pc) ALMA Band 7 observations covering the dust continuum and [C ii] λ157.7 μm emission in four z ∼4.4-4.8 sub-millimeter galaxies (SMGs) selected from the ALESS and AS2UDS ...
A First Look at BISTRO Observations of the ρ Oph-A core
(2018-05-16)
We present 850 μm imaging polarimetry data of the ρ Oph-A core taken with the Submillimeter Common-User Bolometer Array-2 (SCUBA-2) and its polarimeter (POL-2) as part of our ongoing survey project, -fields In STar forming ...
Smooth HI Low Column Density Outskirts In Nearby Galaxies
(2018-05-14)
The low column density gas at the outskirts of galaxies as traced by the 21 cm hydrogen line emission (H i) represents the interface between galaxies and the intergalactic medium, i.e., where galaxies are believed to get ...
