Multi-year characterisation of the broad-band emission from the intermittent extreme BL Lac 1ES~2344+514

H. Abe, S. Abe, V. A. Acciari +232

The BL Lac 1ES 2344+514 is known for temporary extreme properties (e.g., a shift of the synchrotron SED peak energy above 1keV). While those extreme states were so fa…

A fast radio burst source at a complex magnetised site in a barred galaxy

H. Xu, J. R. Niu, P. Chen +71

Fast radio bursts (FRBs) are highly dispersed millisecond-duration radio bursts. Recent observations of a Galactic FRB suggest that at least some FRBs originate from magnetars, but…

The First Post-Kepler Brightness Dips of KIC 8462852

Tabetha S. Boyajian, Roi Alonso, Alex Ammerman +203

We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometr…

A Spitzer Survey for Dust in Type IIn Supernovae

Ori D. Fox, Roger A. Chevalier, Michael F. Skrutskie +6

Recent observations suggest that Type IIn supernovae (SNe IIn) may exhibit late-time (>100 days) infrared (IR) emission from warm dust more than other types of core-collapse SNe. M…

The M-sigma and M-L Relations in Galactic Bulges and Determinations of their Intrinsic Scatter

Kayhan Gultekin, Douglas O. Richstone, Karl Gebhardt +13

We derive improved versions of the relations between supermassive black hole mass (M_BH) and host-galaxy bulge velocity dispersion (sigma) and luminosity (L) (the M-sigma and M-L r…

Constraints on Circumstellar Material Around the Type Ia Supernova 2007af

Joshua D. Simon, Avishay Gal-Yam, Bryan E. Penprase +9

Patat et al. recently inferred the existence of circumstellar material around a normal Type Ia supernova (SN) for the first time, finding time-variable Na I D absorption lines in t…
