2018-2-13 – Seminar by Ben Mather (DIAS)

13 February 2018Seminar

When: 16:00 on Tuesday, 13th February 2018
Where: DIAS, Geophysics Section, 5 Merrion Square, Dublin 2, (library)

Speaker: Ben Mather (DIAS, Dublin, Ireland)
Title: Estimating the depth to the Curie isotherm: a synthesis of the methodology and its application to Ireland.

Abstract:

Magnetic data is one of the most common geophysics datasets available on the surface of the Earth. At long wavelengths it pertains information on the depth at which rocks lose their magnetism. This is called the Curie depth – often interpreted as the 580C isotherm, which is the Curie point of magnetite. In this talk I will outline the methodologies to compute Curie depth and the resolution of thermal structures it can detect. The ongoing acquisition of the magnetic anomaly by Tellus presents a unique opportunity to glean precise estimates of the 580C isotherm, which can be assimilated into large scale thermo-chemical models of the lithosphere.

Earthquakes and other Geohazards

Despite its lack of large earthquakes, Ireland holds a special place in the history of Earthquake studies thanks to the pioneering work of Robert Mallet in the mid-19th century. Come see the past and present of live earthquake monitoring worldwide, from the heart of Dublin.

Location: Dublin Institute for Advanced Studies, 5 Merrion Square, Dublin 2

Date: 16th November 2017

Time: 19:00 – 20:00 and 20:30 – 21:30

There are a limited number of tickets for this FREE event. Please go to:

Hallowe’en Night 2017 – Tuesday 31st October, 18:30-20:00 : Don’t Be Afraid of the Dark (Matter)

Don’t Be Afraid of the Dark (Matter)

Dublin Institute for Advanced Studies (DIAS) will hold a special event this Hallow’en Night exploring the spooky dark matter that surrounds us.

Tuesday 31st October has been designated as International Dark Matter Day – to coincide with Hallowe’en. DIAS’ event will take place from 6.30pm to 8pm at 10 Burlington Road, Dublin 4.

Dark Matter

The evidence for Dark Matter (and the even more mysterious dark energy) has been steadily accumulating since the 1930s and we now believe that less than 5% of the universe is made of the “normal” matter that physicists study in the laboratory. The nature of the dark matter is one of the greatest mysteries in modern physics and will be discussed by the Directors of the DIAS schools of Cosmic Physics, Professor Luke Drury, and Theoretical Physics, Professor Werner Nahm as a dialogue between astrophysics and particle physics.

The event is free to attend, and you can register now at Eventbrite
