Impact of beam-beam effects on absolute luminosity calibrations at the CERN Large Hadron Collider

Tatiana Pieloni, Claudia Tambasco

At the Large Hadron Collider (LHC), absolute luminosity calibrations obtained by the van der Meer (vdM) method are affected by the mutual electromagnetic interaction of the two beams. The colliding bunches experience relative orbit shifts, as well as optic ...

Gaia Data Release 1 Summary of the astrometric, photometric, and survey properties

Stephan Morgenthaler, Shuangqing Liao

Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illu ...

Microlensing of the broad line region in 17 lensed quasars

Frédéric Courbin, Georges Meylan

When an image of a strongly lensed quasar is microlensed, the different components of its spectrum are expected to be differentially magnified owing to the different sizes of the corresponding emitting region. Chromatic changes are expected to be observed ...

Absolute luminosity measurements with the LHCb detector at the LHC

Jian Wang, Olivier Schneider, Yi Zhang, Lei Zhang, Aurelio Bay, Guido Haefeli, Jessica Prisciandaro, Tatsuya Nakada, Christoph Frei, Mark Tobin, Frédéric Blanc, Minh Tâm Tran, Michel De Cian, Vladislav Balagura, Plamen Hristov Hopchev, Frédéric Guillaume Dupertuis, Julien Rouvinet, Christophe Salzmann, Pierre Jaton, Barinjaka Rakotomiaramanana, Joël Bressieux, Raluca Anca Muresan, Johan Luisier, Anne Keune, Vincent Fave, Christophe Bauer, Mathias Oleg Knecht, Neal Gauvin, Raphael Märki

Absolute luminosity measurements are of general interest for colliding-beam experiments at storage rings. These measurements are necessary to determine the absolute cross-sections of reaction processes and are valuable to quantify the performance of the ac ...

Resolving The Stellar Outskirts Of M81: Evidence For A Faint, Extended Structural Component

Pascale Jablonka

We present a wide field census of resolved stellar populations in the northern half of M81, conducted with Suprime-Cam on the 8 m Subaru telescope and covering an area similar to 0.3 deg(2). The resulting color-magnitude diagram reaches over one magnitude ...

The evolution of the brightest cluster galaxies since z similar to 1 from the ESO Distant Cluster Survey (EDisCS)

Pascale Jablonka

We present K-band data for the brightest cluster galaxies (BCGs) from the ESO Distant Cluster Survey (EDisCS). These data are combined with the photometry published by Aragon Salamanca, Baugh & Kauffmann and a low-redshift comparison sample built from the ...

Charge transport across organic-organic interfaces in organic light-emitting diodes

Libero Zuppiroli, Hocine Houili

The process of hopping transport across organic heterojunctions is critical to the function of organic light-emitting diodes (OLED) and many other currently developed organic electronic devices. We consider the case of a hole-only or homopolar heterojuncti ...
