Cosmological Constraints from the double source plane lens SDSSJ0946+1006
We present constraints on the equation of state of dark energy, , and the
total matter density, , derived from the
double-source-plane strong lens SDSSJ0946+1006, the first cosmological
measurement with a galaxy-scale double-source-plane lens. By modelling the
primary lens with an elliptical power-law mass distribution, and including
perturbative lensing by the first source, we are able to constrain the
cosmological scaling factor in this system to be ,
which implies for a flat
cold dark matter (CDM) cosmology. Combining with a cosmic microwave
background prior from Planck, we find = assuming a
flat CDM cosmology. This inference shifts the posterior by 1 and
improves the precision by 30 per cent with respect to Planck alone, and
demonstrates the utility of combining simple, galaxy-scale
multiple-source-plane lenses with other cosmological probes to improve
precision and test for residual systematic biases.Comment: 9 Pages, 7 Figures. Updated version as published in MNRA
Resolving on 100 pc scales the UV-continuum in Lyman- emitters between redshift 2 to 3 with gravitational lensing
We present a study of seventeen LAEs at redshift 23 gravitationally
lensed by massive early-type galaxies (ETGs) at a mean redshift of
approximately 0.5. Using a fully Bayesian grid-based technique, we model the
gravitational lens mass distributions with elliptical power-law profiles and
reconstruct the UV-continuum surface brightness distributions of the background
sources using pixellated source models. We find that the deflectors are close
to, but not consistent with isothermal models in almost all cases, at the
-level. We take advantage of the lensing magnification (typically
20) to characterise the physical and morphological properties of
these LAE galaxies. From reconstructing the ultra-violet continuum emission, we
find that the star-formation rates range from 0.3 to 8.5 M yr
and that the galaxies are typically composed of several compact and diffuse
components, separated by 0.4 to 4 kpc. Moreover, they have peak star-formation
rate intensities that range from 2.1 to 54.1 M yr kpc.
These galaxies tend to be extended with major axis ranging from 0.2 to 1.8 kpc
(median 561 pc), and with a median ellipticity of 0.49. This morphology is
consistent with disk-like structures of star-formation for more than half of
the sample. However, for at least two sources, we also find off-axis components
that may be associated with mergers. Resolved kinematical information will be
needed to confirm the disk-like nature and possible merger scenario for the
LAEs in the sample.Comment: 19 pages, 7 figures, accepted for publication on MNRA
\u3ci\u3eThe Echo of Odin: Norse Mythology and Human Consciousness\u3c/i\u3e by Edward W.L. Smith

Tarot and T.S. Eliot in Stephen King\u27s Dark Tower Novels [Article]
Characters and events in King’s Dark Tower series are inspired by the Fisher King, Arthurian, and other mythologies and legends, as well as the works of more contemporary authors who derived inspiration from similar sources. This paper explores King\u27s use of Tarot motifs in the Dark Tower series with attention to similarities and parallels to the presentation of Tarot in T.S. Eliot\u27s The Waste Land. King’s central character Roland, whose cards are read by his nemesis, has the satisfaction of knowing when the cartomancer is dead and of saving multiple universes, but then discovers that he is doomed to keep saving those universes over and over again
