Understanding BL Lacertae objects [PDF]
Astronomy and Astrophysics, 2010 Context. We present evidence that parsec-scale jets in BL Lac objects may be significantly distinct in kinematics from their counterparts in quasars. We argued this previously for the BL lac sources 1803+784 and 0716+714 and report here a similar pattern for another well-known BL Lac object, PKS 0735+178, whose nuclear jet is found to exhibit ...S.

, 1991 The investigation of the host galaxies of BL Lac objects (BL Lacs) is a promising new field made practical in recent years by advances in detector technology and improved telescope siting.Abraham, Roberto G., Abraham, R.Gcore +1 more sourceA BL Lacertae Object at a Cosmic Age of 800 Myr [PDF]
The Astrophysical Journal Letters, 2021 Abstract We report the discovery of the BL Lacertae object FIRST J233153.20+112952.11 at redshift >6 using near-infrared spectroscopy and broadband observations in the infrared, submillimeter, and radio wavelengths. The detection of the continuum break at ∼0.92 μm in the near-infrared spectrum of FIRST J233153.20+112952.11 provides an Ekaterina Koptelova, Chorng-Yuan Hwangopenaire +1 more sourceNew Observations of BL Lacertae Objects [PDF]
Symposium - International Astronomical Union, 1996 This contribution is divided into three parts: 1. A summary of mostly published work that describes the new type of BL Lac Objects discovered with X-ray satellites, “X-ray Bright BL Lacs (XBLs)”, and their relationship to the previously known “radio bright BL Lacs (RBLs).” Most (but not all?) of the differences between XBLs and RBLs are explicable ...G.

Symposium - International Astronomical Union, 1996 We have analyzed the X-ray spectra of all BL Lacs observed (as pointed or serendipitous sources) by ROSAT. Spectral indices were obtained from the hardness ratios given in the WGA catalogue, a large list of X-ray sources generated from all the ROSAT PSPC pointed observations. The selection of the objects was done by cross-correlating the first revision Padovani, Paolo, Giommi, Paoloopenaire +4 more sourcesDiscovery of very high energy gamma-ray emission from the low-frequency-peaked Bl Lacertae object Bl Lacertae [PDF]
, 2007 The MAGIC collaboration observed BL Lacertae for 22.2 hr during 2005 August to December and for 26 hr during 2006 July to September. The source is the historical prototype and eponym of a class of low-frequency-peaked BL Lacertae (LBL) objects.Sillanpaa A, O.
