Robert Campion: Edmund Campion's Brother?
No full textIn a recent, short monograph, Leslie Campion has attempted to link Edmund Campion to his namesake, the son of an Edmund Campion of Sawston, Cambs., who (Edmund Sr) died in 1544. The argument, though circumstantial, is plausible. However, one piece of additional evidence is not considered—nor could the author have been aware of it. This is the Oxford apprenticeship indenture of one Robert ‘Campian’ to Christopher Noke, freemason, made on 4 October 1579, which is printed below. There Robert is identified as the son of an Edmund Campian, late of London, stationer, deceased. This, of itself, would suggest that Robert was a brother of the Jesuit, and, indeed, the newly proposed Campion pedigree indicates a Robert Campion as an older brother of Edmund. Unfortunately, this would require our apprentice to be over 40 years old! A more likely candidate is a Robert Campian, aged ca 14 years, who made a deposition before the University (Vice-) Chancellor's court on 8 January 1573 regarding William Goodyere, Under Butler of St John's College. The connection to St John's is, of course, significant, as is the apprenticeship to Noke, who was suspected of recusancy in 1577. Thus, it is tempting to join the two Oxford Roberts together and to identify him as Edmund Campion's younger brother, but, if we do, then we must look for an Edmund Sr who lived into the later 1550s at least. Additional investigation would be needed to determine where (or whether) he could be grafted on to Leslie Campion's tree, but the name ‘Robert’ requires at least a reexamination of the Witham branch, and the author himself seems to allow this possibility (p. 55). As for Robert Campian, the apprentice freemason, he cannot be traced in later Oxford records in spite of the provision for his subsequent entrance into the craft guild and the freedom of the City.</jats:p

How undemocratic is the House of Lords?
No full textSonali Campion, Sean Kippin and the Democratic Audit team examine how the UK’s deeply controversial current second chamber, the House of Lords, matches up to the criteria for liberal democracies with bicameral legislatures. Now an almost-all appointed Chamber, the Lords has achieved recent prominence on Brexit and tax credits by exerting some bipartisan influence moderating Commons proposals. However, its members remain creatures of patronage, and wholly unaccountable to the UK’s citizens. All parties except the Tories now support its replacement by an elected Senate. Increasingly only the Tories and Liberal Democrats are still appointing any peers – although there are also a fifth of peers who are ‘crossbenchers’, not taking a party whip

Neutrino emission via proton-proton interaction and magnetic field screening in GRBs
No full textGamma-Ray Bursts (GRBs) are one of the most energetic astrophysical events of our Universe and a
precise study of all the physical mechanisms occuring in these systems involves different branches of
physics (from particles physics to General Relativity). The main subjects of this thesis concern the
particles physics and the plasma physics fields. I study two different physical processes, operated by
elementary particles as protons, electron/positron paris, photons and neutrinos, occuring in GRBs.
In Ch. (1) I give a general introduction to GRBs, with some of their structural physical generalities
and properties (as their different emission phases, spectral and temporal properties etc.). I introduce also
the fireshell model, which has been developed during the years by Prof. Ruffini, R. and his group, in
order to study and understand the several mechanisms behind the GRB emission. I will also highlight the
principal differences between this model and the fireball model (which was the first model adopted in
order to study the GRBs emission).
The structure of the fireshell model considers a Reissner-Nordoström Black Hole, with a strong electric
field that converts part of the BH total energy in e + e − plasma by the vacuum polarization process. These
particles are accelerated and emit photons, and this leads to the formation of a relativistic optically thin
fireshell of e + e − γ plasma (the “PEM–pulse”). This shell interacts with baryons, deposited in the ambient
near the BH due to the collapse event, forming a new accelerated optically thick plasma of e + e − γ-baryons
(PEMB–pulse). The transparency of this shell brings to the formation of the proper GRB emission
(P-GRB emission).
In Ch. (2) I introduce a classification of the GRBs in classes and subclasses. They differ from each
other principally for their different progenitors, formation process, their isotropic energy E iso , their rest-
frame spectral peak energy E p,i and local observed rate.
In the Thesis, I have focused my attention principally on a particular type of long GRB class: the type
I Binary-driven HyperNova (BdHN). The physical scenario and process, that leads to the formation of
the BdHN class, is the Induced Gravitational Collapse (IGC), with the hypercritical accretion process
paradigm. The two original studies of the Thesis, developed in Chs. (3) and (4), are based on the physical
scenario of BdHN. In this chapter, I also show the connections between the several observations of a GRB
event and the basic processes of the BdHN model.
In Ch. (3), the first topic of the Thesis is presented, namely the neutrinos and photons production by
proton-proton interaction, between accelerated protons and protons at rest. Keeping in mind the above
discussed scenario for the dynamics of the e + e − γ-baryons plasma, recent numerical simulations have
shown that the SN ejecta becomes highly asymmetric. Therefore, the electron-positron (e ± ) plasma
created in the BH formation, during its isotropic and self-accelerating expansion, engulfs different
amounts of ejecta baryons along different directions, leading to a direction-dependent Lorentz factor. In
this configuration, I have studied the pp interaction occurring in two regions: an high density region and a
low density region. In the conclusion of this chapter I also try to give an estimate of a possible, direct or
indirect, detection of the neutrinos and photons created throught the above mechanism. From this analysis
it came out that a possible detection of these neutrinos with currently operating detectors is plausible only
for sources several order of magnitude more energetic than the ones considered in this work, and very-high
energy ineracting protons (this subject is treated in App. (D) and will be better developed in future works).
It also came out that an indirect detection of these neutrinos by means of the related photons emission is
possible.
The second subject of the Thesis is presented in Ch. (4) and concerns the study of the screening
process of an electromagnetic field near a BH operated by electron-positron pairs. It has been shown
that a rotating BH immersed in a test background magnetic field, of initial strength B 0 and aligned
parallel to the BH rotation axis, generates an induced electric field, whose strength is proportional to the
background magnetic field, E = 1/2 ΥB (where Υ is the BH spin parameter). In this analysis, I consider
the configuration of crossed fields: B = Bẑ and E = E ŷ. In this system, an huge number of e + e − pairs can be emitted by vacuum polarization process, start to be accelerated to high energies by the induced electric
field and emit synchrotron photons. These photons interact with the magnetic field via the magnetic pair
production process (MPP): γ + B → e + + e − . The motion of all these particles around the magnetic field
lines generates also an induced magnetic field oriented in the opposite direction to the background one,
which implies a reduction of the background magnetic field. The principal results are that the combination
of the processes described above can reduce the magnetic field in a small time scale, even if the production
of pairs is not so efficient due to the low energy of the emitted photons, for the selected initial conditions
of the field strengths and particles densities
