Radiation and Polarization Signatures of 3D Multi-zone Time-dependent Hadronic Blazar Model
Haocheng Zhang, Chris Diltz, Markus Böttcher
We present a newly developed time-dependent three-dimensional multi-zone hadronic blazar emission model. By coupling a Fokker-Planck based lepto-hadronic particle evolution code 3D…
LeptoHadronic Origin of -ray Outbursts of 3C 279
Vaidehi S. Paliya, Chris Diltz, Markus Bottcher +2
The blazar 3C 279 exhibited a giant -ray outburst in 2013 December and 2014 April. Apart from the very fast -ray flux variability, the spectral nature of the flares were also…
A hard gamma-ray flare from 3C 279 in 2013 December
Vaidehi S. Paliya, Chris Diltz, Markus Bottcher +2
The blazar 3C 279 exhibited twin -ray flares of similar intensity in 2013 December and 2014 April. In this work, we present a detailed multi-wavelength analysis of the 2013 Dece…
Violent Hard X-ray Variability of Mrk 421 Observed by NuSTAR in 2013 April
Vaidehi S. Paliya, Markus Bottcher, Chris Diltz +3
The well studied blazar Markarian 421 (Mrk 421, =0.031) was the subject of an intensive multi-wavelength campaign when it flared in 2013 April. The recorded X-ray and very high…
Time Dependent Hadronic Modeling of Flat Spectrum Radio Quasars
Christopher Diltz, Markus Boettcher, Giovanni Fossati
We introduce a new time-dependent lepto-hadronic model for blazar emission that takes into account the radiation emitted by secondary particles, such as pions and muons, from photo…
Time Dependent Leptonic Modeling of Fermi II Processes in the Jets of Flat Spectrum Radio Quasars
Christopher Diltz, Markus Boettcher
In this paper, we discuss the light-curve features of various flaring scenarios in a time-dependent leptonic model for low-frequency-peaked blazars. The quasar 3C273 is used as an…
Multi-wavelength observations of blazar AO 0235+164 in the 2008-2009 flaring state
M. Ackermann, M. Ajello, J. Ballet +208
The blazar AO 0235+164 (z = 0.94) has been one of the most active objects observed by Fermi Large Area Telescope (LAT) since its launch in Summer 2008. In addition to the continuou…
The first Fermi multifrequency campaign on BL Lacertae: characterizing the low-activity state of the eponymous blazar
A. A. Abdo
We report on observations of BL Lacertae during the first 18 months of Fermi-LAT science operations and present results from a 48-day multifrequency coordinated campaign from 2008…
Multi-wavelength Observations of the Flaring Gamma-ray Blazar 3C 66A in 2008 October
LAT collaboration, A. A. Abdo et al., the VERITAS collaboration +4
The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GA…
Another look at the BL Lacertae flux and spectral variability
C. M. Raiteri, M. Villata, L. Bruschini +52
The GLAST-AGILE Support Program (GASP) of the Whole Earth Blazar Telescope (WEBT) monitored BL Lacertae in 2008-2009 at radio, near-IR, and optical frequencies. During this period,…
