\nTitle: Classical scale invariance and inflation <\/p>\n
Abstract:<\/p>\n
Classical scale invariance was applied to inflationary model building already from the very first papers. Recently the use of dynamically induced inflaton potentials \u00e0 la Coleman-Weinberg became again fashionable. In the light of this, we study different applications of classical scale invariance to inflation. Depending on whether classical scale invariance is a property of the full action or just of the scalar potential, we consider three different realizations of Coleman-Weinberg inflation in presence of a non-minimal coupling of the inflaton to gravity. For each realization, we present the most relevant inflationary predictions and distinctive features. <\/p>\n

Emergency light testing.<\/strong><\/h2>\n We have been informed by Facilities that the emergency lights in the Physics building will be tested next week. This shouldn’t be disruptive, but be aware some lights may need to be turned off for a few minutes. <\/p>\n

Safety Induction.<\/strong><\/h2>\n Safety inductions take place on the first working Thursday of the month. The next induction takes place on 2nd February in C29 Physics, starting at 2:30 pm and running for approximately 1 hr. If you are a new member of staff or just want a refresher please come along.<\/p>\n

Legionella prevention<\/strong><\/h2>\n Water Hygiene and Shower head cleaning <\/strong>in the Physics Building <\/strong>will take place week commencing Monday 30th January <\/strong>from 9am daily.
\nTwo Lancaster University engineers will require access to kitchens and shared bathrooms to test hot water temperatures. The engineers will not test every kitchen\/bathroom just a sample from different locations within the building. This brief survey will take approximately five minutes, and is to ensure that the hot water is maintained at the correct temperature to prevent any instances of legionella. There will be no shutdown of service.<\/p>\nShonah Ion<\/strong><\/p>\n<\/p>\n
Physically Speaking Talk<\/strong><\/h2>\nThe next Physically Speaking talk will be on Wednesday 25th January at 4pm in the Cavendish Colloquium Room (in the Faraday building). Carley Martin and Andy Wharton will talk about Saturn’s Magnetosphere and CP-violation at ATLAS. The talks will be accessible to students from all areas of physics, so if you want to learn more about different areas of physics then come along, and enjoy some discussion with coffee and biscuits afterwards.<\/p>\n
Thanks!\n<\/p>\n

\n<\/strong>Title: Jets from Compact Binary Mergers: Electromagnetic Counterparts to Gravitational Wave Sources<\/p>\n\nSpeaker: Gavin Lamb (Liverpool John Moores University)<\/p>\n

Abstract:
\n Short gamma-ray bursts are believed to be produced by ultra-relativistic jets launched from the merger of neutron stars (NSNS) or a black-hole and a neutron star (BHNS). A short (<2s) flash of gamma-rays, from internal shocks, is followed by a multi-band afterglow from external shocks as the jet decelerates in the ambient medium. Observations of the afterglow are currently triggered by the prompt gamma-rays. For jets with a bulk Lorentz factor <30 the prompt gamma-rays would be suppressed, resulting in an orphan afterglow as the jet decelerates. If low-Lorentz factors dominate the distribution of merger jets, then gravitational wave triggers from NSNS(BHNS) mergers will reveal a hidden population of failed short gamma-ray bursts. The electromagnetic counterparts to gravitational wave detected NSNS(BHNS) mergers can be used to determine the Lorentz-factor distribution, opening-angle, and structure of such jets.\n <\/p>\n

VC Visit<\/strong><\/h2>\nThe VC will visit Physics on Tues 21 February from 1300-1500hrs. The format and venues for the visit are given below and I’d be grateful if you could make a note in your diaries.<\/p>\n
Part One (1300 \u2013 1345hrs) Venue \u2013 B10<\/strong>
\n Head of department and their leadership\/management team<\/strong>
\n The two questions Mark wants to discuss are:
\n 1. Their reflections on the NSS 2016 outcomes, the strengths and weaknesses and work they have done ready for NSS 2017.
\n2. In the strategy refresh what they as department they would like to see added\/updated.<\/p>\nPart Two (1345 \u2013 1500hrs) Venue – C36<\/strong>
\n Whole department <\/strong>
\n Mark will talk for approximately 25 minutes followed by general questions from the department.<\/p>\nGr\u00e1inne Wilkinson<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"February Safety Induction February’s safety induction will take place on February 2nd in C29 starting at 2pm.
