SCUBA-2 overdensities associated with candidate protoclusters selected from Planck data
T. Cheng, D. L. Clements, J. Greenslade +21
We measure the 850-m source densities of 46 candidate protoclusters selected from the Planck High-z catalogue (PHz) and the Planck Catalogue of Compact Sources (PCCS) that were…
SCUBA-2 observations of candidate starbursting protoclusters selected by Planck and Herschel-SPIRE
T. Cheng, D. L. Clements, J. Greenslade +21
We present SCUBA-2 850-m observations of 13 candidate starbursting protoclusters selected using Planck and Herschel data. The cumulative number counts of the 850-m sources in…
Adaptive optics assisted near-infrared polarization measurements of sources in the Galactic Center
Rainer M. Buchholz, Gunther Witzel, Rainer Schödel +3
The goals of this work are to provide NIR polarimetry of the stellar sources in the central pc at the resolution of an 8m telescope for the first time, along with new insights into…
The extreme luminosity states of Sagittarius A*
N. Sabha, G. Witzel, A. Eckart +10
We discuss mm-wavelength radio, 2.2-11.8um NIR and 2-10 keV X-ray light curves of the super massive black hole (SMBH) counterpart of Sagittarius A* (SgrA*) near its lowest and high…
Near infrared flares of Sagittarius A*: Importance of near infrared polarimetry
M. Zamaninasab, A. Eckart, G. Witzel +11
We report on the results of new simulations of near-infrared (NIR) observations of the Sagittarius A* (Sgr A*) counterpart associated with the super-massive black hole at the Galac…
