Kavli Affiliate: Roger W. Romani | First 5 Authors: Hongjun An, Roger W. Romani, , , | Summary: We report on X-ray measurements constraining the spectral energy distribution (SED) of the high-redshift $z=5.18$ blazar SDSS J013127.34$-$032100.1 with new XMM-Newton and NuSTAR exposures. The blazar’s X-ray spectrum is well fit by a power law with $Gamma=1.9$ […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Kielan K. Wilcomb, Quinn M. Konopacky, Travis S. Barman, Christopher A. Theissen, Jean-Baptiste Ruffio | Summary: We present moderate-resolution ($Rsim4000$) $K$ band spectra of the "super-Jupiter," $kappa$ Andromedae b. The data were taken with the OSIRIS integral field spectrograph at Keck Observatory. The spectra reveal resolved molecular […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, Alexei V. Filippenko, Thomas G. Brink, WeiKang Zheng | Summary: We analyze photometry and spectra of the "redback" millisecond pulsar binary J2339$-$0533. These observations include new measurements from Keck and GROND, as well as archival measurements from the OISTER, WIYN, SOAR, […]
