The Square Kilometre Array Observatory (SKAO) will explore the radio sky to new depths in order to conduct transformational science. SKAO data products made available to astronomers will be correspondingly large and complex, requiring the application

Regional ischaemia following acute head injury

Autor: Coles, J. P.

15Oxygen positron emission tomography (15O PET) has been used to demonstrate ischaemia and define physiological thresholds predictive of tissue viability in stroke. Unfortunately, it is difficult to translate such data to clinical head injury due to

COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses IX. Time delays, lens dynamics and baryonic fraction in HE 0435-1223

Autor: Courbin, F., Chantry, V., Revaz, Y., Sluse, D., Faure, C., Tewes, M., Eulaers, E., Koleva, M., Asfandiyarov, I., Dye, S., Magain, P., van Winckel, H., Coles, J., Saha, P., Ibrahimov, M., Meylan, G.

We present accurate time delays for the quadruply imaged quasar HE 0435-1223. The delays were measured from 575 independent photometric points obtained in the R-band between January 2004 and March 2010. With seven years of data, we clearly show that

The Hubble time inferred from 10 time-delay lenses

Autor: Saha, P., Coles, J., Maccio', A. V., Williams, L. L. R.

Publikováno v: Astrophys.J.650:L17-L20,2006

We present a simultaneous analysis of 10 galaxy lenses having time-delay measurements. For each lens we derive a detailed free-form mass map, with uncertainties, and with the additional requirement of a shared value of the Hubble parameter across all
