GOAL

The goal of this project is to study and constrain the pair halo emission of AGN using the 2FHL catalog (E>50 GeV) and the preliminary results for the '3FHL' catalog.

SOURCE SAMPLES

We have considered the 2FHL and the 3FHL catalog and we have created three different samples of sources.

 

E>50 GeV

E>10 GeV

Low z

all z<0.15 |b|>15 (39)

BL Lacs z<0.15 |b|>20 (43)

High z

all z>0.4 |b|>15 (27)

BL Lacs z>0.70 |b|>20 (43)

All

all with |b|>20 (198)

BL Lacs with |b|>20 (90)

The three cases are labelled as "Low z", "High z" and "All" and the number of sources in each sample is reported in parenthesis. 

2FHL: We have always considered all AGN and the most of them are BL Lacs

3FHL: We have considered only BL Lacs.

Therefore our catalog of sources is largely given by BL Lacs.

 

METHOD

Given the above listed samples we have simulated the Galactic diffuse gamma-ray emission and the isotropic diffuse together with the emission from the selected sources.
