[Alumnos] Agenda semanal de Ciencia y Técnica

[Secretaría de Ciencia y Técnica - FCAGLP]

Hola a todos,

Este es el resumen de las actividades científicas que tendremos la 
semana próxima en nuestra Facultad.

Agenda Semanal de Ciencia y Técnica


  *

    Lunes 2 de mayo - 13 hs, Salón Meridiano:


SEMINARIO:Andreas Güntner

German Research Centre for Geosciences (GFZ Potsdam, Germany)

Título: Monitoring water storage changes with ground- and 
satellite-based gravimetry

Resumen:

In this lecture, I will give an overview on recent research activities 
in the field of hydro-gravimetry. Variations of water storage on or 
below the Earth surface are related to mass variations, which in turn 
cause variations of the Earth's gravity field. By monitoring the 
time-variable gravity field of the Earth, the satellite missions GRACE 
(since 2002) and its successor GRACE-FollowOn (to be launched in 2017), 
provide unique integrative information on the hydrological cycle at the 
global scale, and for large river basins and aquifers. Similarly, 
high-precision measurements with gravimeters on the ground, in 
particular with superconducting gravimeters, allow for monitoring water 
storage changes at the local scale of several 100 meters around the 
instrument. I will illustrate the measurement principles of time-lapse 
gravimetry from ground and space, and present examples of hydrological 
applications for assessing the water balance, long-term changes in the 
hydrological cycle, or the impact of hydrological extreme events.

SEMINARIO: Joseph Anderson

European Southern Observatory, Chile.


Título: Type II supernovae: progenitors, diversity, and their use as 
probes of the Universe

Resumen:

Massive stars that reach the end of their lives with their hydrogen 
envelopes intact explode as type II supernovae (SNe II). SNe II are the 
most populous terminal stellar explosion in the Universe. The short 
lives of SNe II make them a direct tracer of massive star formation 
within galaxies, and their energetics affect their environments and 
hence galaxy evolution and dynamics. The intrinsic brightness of SNe II 
also make them useful probes of other processes in the Universe. SN II 
progenitors have been constrained to be red supergiant stars through 
their direct detection on pre-explosion images. However, it is currently 
unclear how the large diversity observed in their light-curves and 
spectra is linked to progenitor properties such as mass, metallicity, 
extent of the hydrogen envelope, or the role of binary interaction.

In this seminar I will discuss the our current knowledge of these 
explosions, focusing on studies of large samples of SNe, attempting to 
constrain the diversity of a range of observed transient parameters, and 
mapping these to progenitor and explosion properties. I will also 
discuss the use of SNe II as Astrophysical probes, concentrating on 
their application to measuring extra-galactic metallicities. I will 
finish with a look to current and future projects that attempt to 
further our knowledge of these massive star explosions.
