The 2 Ms Chandra Deep Field-North Survey and the 250 ks Extended Chandra Deep Field-South Survey: Improved Point-source Catalogs
Lehmer, B. D.; Alexander, D. M.; Bauer, F. E. +4 more
We present improved point-source catalogs for the 2 Ms Chandra Deep Field-North (CDF-N) and the 250 ks Extended Chandra Deep Field-South (E-CDF-S) Surveys, implementing a number of recent improvements in Chandra source-cataloging methodology. For CDF-N/E-CDF-S, we provide a main catalog that contains 683/1003 X-ray sources detected with wavdetect …
Magnetohydrodynamic Oscillations in the Solar Corona and Earth's Magnetosphere: Towards Consolidated Understanding
Zimovets, I. V.; Nakariakov, V. M.; Jelínek, P. +9 more
Magnetohydrodynamic (MHD) oscillatory processes in different plasma systems, such as the corona of the Sun and the Earth's magnetosphere, show interesting similarities and differences, which so far received little attention and remain under-exploited. The successful commissioning within the past ten years of THEMIS, Hinode, STEREO and SDO spacecra…
Robust forecasts on fundamental physics from the foreground-obscured, gravitationally-lensed CMB polarization
Peiris, Hiranya V.; Feeney, Stephen M.; Errard, Josquin +1 more
Recent results from the BICEP, Keck Array and Planck Collaborations demonstrate that Galactic foregrounds are an unavoidable obstacle in the search for evidence of inflationary gravitational waves in the cosmic microwave background (CMB) polarization. Beyond the foregrounds, the effect of lensing by intervening large-scale structure further obscur…
Kinematic Sunyaev-Zel'dovich Effect with Projected Fields: A Novel Probe of the Baryon Distribution with Planck, WMAP, and WISE Data
Spergel, David N.; Ferraro, Simone; Hill, J. Colin +2 more
The kinematic Sunyaev-Zel'dovich (KSZ) effect—the Doppler boosting of cosmic microwave background (CMB) photons due to Compton scattering off free electrons with nonzero bulk velocity—probes the abundance and the distribution of baryons in the Universe. All KSZ measurements to date have explicitly required spectroscopic redshifts. Here, we impleme…
Planck 2015 results. XII. Full focal plane simulations
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +228 more
We present the 8th full focal plane simulation set (FFP8), deployed in support of the Planck 2015 results. FFP8 consists of 10 fiducial mission realizations reduced to 18 144 maps, together with the most massive suite of Monte Carlo realizations of instrument noise and CMB ever generated, comprising 104 mission realizations reduced to a…
Planck intermediate results. XXIX. All-sky dust modelling with Planck, IRAS, and WISE observations
Kneissl, R.; Miville-Deschênes, M. -A.; Boulanger, F. +195 more
We present all-sky modelling of the high resolution Planck, IRAS, and WISE infrared (IR) observations using the physical dust model presented by Draine & Li in 2007 (DL, ApJ, 657, 810). We study the performance and results of this model, and discuss implications for future dust modelling. The present work extends the DL dust modelling carried …
The KMOS AGN Survey at High redshift (KASHz): the prevalence and drivers of ionized outflows in the host galaxies of X-ray AGN
Alexander, D. M.; Bauer, F. E.; Swinbank, A. M. +7 more
We present the first results from the KMOS (K-band Multi-Object Spectrograph) AGN (active galactic nuclei) Survey at High redshift (KASHz), a VLT/KMOS integral-field spectroscopic (IFS) survey of z ≳ 0.6 AGN. We present galaxy-integrated spectra of 89 X-ray AGN (L2-10 keV = 1042-1045 erg s-1), for which …
Black hole, neutron star and white dwarf candidates from microlensing with OGLE-III
Soszyński, I.; Udalski, A.; Szymański, M. K. +13 more
Most stellar remnants so far have been found in binary systems, where they interact with matter from their companions. Isolated neutron stars and black holes are difficult to find as they are dark, yet they are predicted to exist in our Galaxy in vast numbers. We explored the OGLE-III data base of 150 million objects observed in years 2001-2009 an…
Tracing the Reionization Epoch with ALMA: [C II] Emission in z ∼ 7 Galaxies
Maiolino, R.; Giavalisco, M.; Castellano, M. +12 more
We present new results on [C II]158 µ {{m}} emission from four galaxies in the reionization epoch. These galaxies were previously confirmed to be at redshifts between 6.6 and 7.15 from the presence of the Lyα emission line in their spectra. The Lyα emission line is redshifted by 100-200 km s-1 compared to the systemic redshift giv…
A survey of the cold molecular gas in gravitationally lensed star-forming galaxies at z > 2
Murphy, E. J.; Weiss, A.; Greve, T. R. +18 more
Using the Australia Telescope Compact Array, we conducted a survey of CO J = 1 - 0 and J = 2 - 1 line emission towards strongly lensed high-redshift dusty star-forming galaxies (DSFGs) previously discovered with the South Pole Telescope (SPT). Our sample comprises 17 sources that had CO-based spectroscopic redshifts obtained with the Atacama Large…
