The execution of William Wallace: Saint Bartholomew’s Eve, Monday 23 August 1305
Bringing William Wallace to London for execution was a departure from normal practice, and the reason seems to have been to have him executed in front of the largest audience possible, and on the feast day of an apostle who had died like one of Wallace's victims
The Montmorencys and the Abbey of Sainte Trinit�, Caen: Politics, Profit and Reform
Female religious, especially holders of benefices, made significant contributions to aristocratic family strategy and fortune in early modern France. This study of members of the wider Montmorency family in the sixteenth and early seventeenth centuries demonstrates the financial and political benefits derived from female benefice holding. Abbey stewards and surintendants of aristocratic households collaborated in the administration of religious revenues. Montmorency control of Sainte Trinit�, the Abbaye aux Dames, Caen, for over a century was associated with attempts to assert political influence in Normandy. Conflict ostensibly over religious reform could have a political dimension. Yet reform could be pursued vigorously by those originally cloistered for mercenary or political reasons
Probing the Low Surface Brightness Dwarf Galaxy Population of the Virgo Cluster
We have used public data from the Next Generation Virgo Survey (NGVS) to
investigate the dwarf galaxy population of the Virgo cluster beyond what has
previously been discovered. We initially mask and smooth the data, and then use
the object detection algorithm Sextractor to make our initial dwarf galaxy
selection. All candidates are then visually inspected to remove artefacts and
duplicates. We derive Sextractor parameters to best select low surface
brightness galaxies using g band central surface brightness values of 22.5 to
26.0 mag sq arc sec and exponential scale lengths of 3.0 - 10.0 arc sec to
identify 443 cluster dwarf galaxies - 303 of which are new detections. These
new detections have a surface density that decreases with radius from the
cluster centre. We also apply our selection algorithm to 'background',
non-cluster, fields and find zero detections. In combination, this leads us to
believe that we have isolated a cluster dwarf galaxy population. The range of
objects we are able to detect is limited because smaller scale sized galaxies
are confused with the background, while larger galaxies are split into numerous
smaller objects by the detection algorithm. Using data from previous surveys
combined with our data, we find a faint end slope to the luminosity function of
-1.35+/-0.03, which does not significantly differ to what has previously been
found for the Virgo cluster, but is a little steeper than the slope for field
galaxies. There is no evidence for a faint end slope steep enough to correspond
with galaxy formation models, unless those models invoke either strong feedback
processes or use warm dark matter.Comment: Accepted for publication in MNRA
Standard Model Higgs Search in the Four Jet Channel at LEP
The Standard Model Higgs boson was searched for at LEP, by the four
collaborations in the year 2000, at centre-of-mass energies from 200-209GeV. An
excess of events, potentially compatible with the production of a Higgs boson
of mass ~115GeV was observed, largely in the four-jet channel. The search in
this channel is discussed in this letter.Comment: 4 pages, 4 figures, 1 tabl
