Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
We report the detection of a transient γ-ray source in the direction of B3 1428+422 (z = 4.72) by analyzing the 110-month Fermi-LAT Pass 8 data. The new transient γ-ray source is far away from the Galactic plane and has a rather soft spectrum, in agreement with being a high redshift blazar. We suggest that the newly discovered transient is the γ-ray counterpart of B3 1428+422, which could be the most distant GeV source detected so far. The detection of a group of such distant γ-ray blazars will be helpful in reconstructing the evolution of the luminosity function and studying the extragalactic background light at such high redshifts.
