An Accreting Black Hole in the Nuclear Star Cluster of the Bulgeless Galaxy NGC 1042
Joseph C. Shields, C. Jakob Walcher, Torsten Boeker +3
We present spectroscopic evidence for a low-luminosity, low-excitation active galactic nucleus (AGN) in NGC 1042, powered by an intermediate-mass black hole. These findings are sig…
Measurement of the rare decay pi0 -> e+ e-
E. Abouzaid
The branching ratio of the rare decay pi0 -> e+ e- has been measured precisely, using the complete data set from the KTeV E799-II experiment at Fermilab. We observe 794 candidate p…
Improved KL->pi e nu Form Factor and Phase Space Integral with Reduced Model Uncertainty
KTeV collaboration, E. Abouzaid
Using the published KTeV sample of 2 million KL-> pi e nu decays and a new form factor expansion with a rigorous bound on higher order terms, we present a new determination of the…
Emission and absorption in Narrow-Line Seyfert 1 Galaxies
Anca Constantin, Joseph C. Shields
The emission and absorption attributes of the UV-blue nuclear spectra of the Narrow-Line Seyfert 1 (NLS1) galaxies are analyzed based on high quality archival HST observations. Mea…
