Space Telescope and Optical Reverberation Mapping Project. IV. Anomalous behavior of the broad ultraviolet emission lines in NGC 5548
M. R. Goad, K. T. Korista, G. De Rosa +99
During an intensive Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) UV monitoring campaign of the Seyfert~1 galaxy NGC 5548 performed from 2014 February to July, the…
Primary black hole spin in OJ287 as determined by the General Relativity centenary flare
M. J. Valtonen, S. Zola, S. Ciprini +87
OJ287 is a quasi-periodic quasar with roughly 12 year optical cycles. It displays prominent outbursts which are predictable in a binary black hole model. The model predicted a majo…
Metallicity from Type II Supernovae from the (i)PTF
F. Taddia, P. Moquist, J. Sollerman +13
Type IIP supernovae (SNe IIP) have recently been proposed as metallicity () probes. The spectral models of Dessart et al. (2014) showed that the pseudo-equivalent width of Fe II…
Evidence for Two Distinct Populations of Type Ia Supernovae
Xiaofeng Wang, Lifan Wang, Alexei V. Filippenko +2
Type Ia supernovae (SNe Ia) have been used as excellent standardizable candles for measuring cosmic expansion, but their progenitors are still elusive. Here we report that the spec…
A Search for "Dwarf" Seyfert Nuclei. VI. Properties of Emission-Line Nuclei in Nearby Galaxies
Luis C. Ho, Alexei V. Filippenko, Wallace L. W. Sargent
We use the database from Paper III to quantify the global and nuclear properties of emission-line nuclei in the Palomar spectroscopic survey of nearby galaxies. We show that the ho…
