Scaling of cosmological domain wall networks with junctions
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We describe the results of the largest and most accurate three-dimensional field theory simulations of domain wall networks with junctions. We consider a previously introduced clas…
Probing the close environment of massive young stars with spectro-astrometry
J. M. C. Grave, M. S. N. Kumar
Aims: We test the technique of spectro-astrometry as a potential method to investigate the close environment of massive young stars. Method: Archival VLT near infrared K band spect…
The evolution of clusters in the CLEF cosmological simulation: X-ray structural and scaling properties
Scott T. Kay, Antonio C. da Silva, Nabila Aghanim +5
We present results from a study of the X-ray cluster population that forms within the CLEF cosmological hydrodynamics simulation, a large N-body/SPH simulation of the Lambda CDM co…
Astrophysical Probes of Fundamental Physics
C. J. A. P. Martins
I review the theoretical motivation for varying fundamental couplings and discuss how these measurements can be used to constrain a number of fundamental physics scenarios that wou…
WFCAM, Spitzer-IRAC and SCUBA observations of the massive star forming region DR21/W75: II. Stellar content and star formation
M. S. N. Kumar, C. J. Davis, J. M. C. Grave +2
Wide field near-infrared observations and Spitzer Space Telescope IRAC observations of the DR21/W75 star formation regions are presented. The photometric data are used to analyse t…
The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST)
M. Guedel, K. R. Briggs, K. Arzner +18
(abridged:) The XMM-Newton Extended Survey of the Taurus Molecular Cloud (XEST) surveys the most populated ~5 square degrees of the Taurus star formation region, using the XMM-Newt…
Cosmic reionization constraints on the nature of cosmological perturbations
Pedro P. Avelino, Andrew R. Liddle
We study the reionization history of the Universe in cosmological models with non-Gaussian density fluctuations, taking them to have a renormalized probability distribution f…
The XMM Cluster Survey: A Massive Galaxy Cluster at z=1.45
S. A. Stanford, A. K. Romer, K. Sabirli +14
We report the discovery of XMMXCS J2215.9-1738, a massive galaxy cluster at z =1.45, which was found in the XMM Cluster Survey. The cluster candidate was initially identified as an…
On the effect of overshooting as predicted by the modelling of the pre-main sequence evolution of a 2 solar-mass star
J. P. Marques, M. J. P. F. G. Monteiro, J. Fernandes
We discuss the effects of convective overshooting in the PMS evolution of intermediate mass stars, by analysing in detail the early evolution towards the main sequence of a 2 M_sun…
Report on the CoRoT Evolution and Seismic Tools Activity
M. K. J. P. F. G. Monteiro, Y. Lebreton, J. Montalban +24
We present the work undertaken by the Evolution and Seismic Tools Activity (ESTA) team of the CoRoT Seismology Working Group. We have focused on two main tasks: Task 1 - now finish…
An Outbursting Protostar of the FU~Orionis type in the Cygnus OB7 Molecular Cloud
T. A. Movsessian, T. Khanzadyan, C. Aspin +5
Context: To follow the early evolution of stars we need to understand how young stars accrete and eject mass. It is generally assumed that the FU Orionis phenomenon is related to t…
Reconstructing the dark energy equation of state with varying couplings
P. P. Avelino, C. J. A. P. Martins, N. J. Nunes +1
We revisit the idea of using varying couplings to probe the nature of dark energy, in particular by reconstructing its equation of state. We show that this method can be far superi…
Frustrated Expectations: Defect Networks and Dark Energy
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We discuss necessary conditions for a network of cosmic domain walls to have a chance of providing the dark energy that might explain the recent acceleration of the universe. We de…
