亮费米LAT Blazar的光谱

Optical Spectroscopy of Bright Fermi LAT Blazars

Michael S. Shaw, Roger W. Romani, Stephen E. Healey, Garret Cotter, Peter F. Michelson, Anthony C. S. Readhead

摘要:

我们报告了最近在{ \it Fermi} LAT亮源列表中发现的$γ$射线耀变体的HET和Palomar 5 m光谱。这些数据提供了10个新发现的$γ$ -射线平谱射电类星体(FSRQ)和6个新的BL Lac以及6个额外的BL Lac的改进光谱的识别。我们大大提高了亮LAT耀变体的识别完整性,给出了新的红移和$z$约束,新的黑洞质量估计和新的光学SED测量。

英文摘要:

We report on HET and Palomar 5 m spectroscopy of recently identified $γ$-ray blazars in the {\it Fermi} LAT Bright Source List. These data provide identifications for 10 newly discovered $γ$-ray flat spectrum radio quasars (FSRQ) and six new BL Lacs plus improved spectroscopy for six additional BL Lacs. We substantially improve the identification completeness of the bright LAT blazars and give new redshifts and $z$ constraints, new estimates of the black hole masses and new measurements of the optical SED.
