标题： SST-1M Observations of Markarian 421

摘要： 马克里安421（Mrk 421）是距离最近且亮度最高的高频峰值类星体之一，红移为z = 0.031。 它是伽马射线的强源，多年来通过来自各种望远镜的多波段观测对其宽波段辐射进行了广泛研究。 Mrk 421一直是SST-1M望远镜观测活动的目标——位于捷克共和国布拉格奥德热沃天文台的两台单镜小型切连科夫望远镜。 这些望远镜以单点和立体模式运行，利用成像大气切连科夫技术（IACT）在1-300 TeV能量范围内探测极高能（VHE）伽马射线。 我们介绍了最近的SST-1M观测、数据分析以及对Mrk 421辐射机制的初步物理建模结果。 显示英文摘要

摘要： Markarian 421 (Mrk 421) is the closest and one of the brightest high-frequency peaked blazars, located at a redshift of z = 0.031. It is a strong source of gamma rays, and its broadband emission has been extensively studied over the years through multi-wavelength observations from various telescopes. Mrk 421 has been a target of observational campaigns conducted by the SST-1M telescopes - two single-mirror small-size Cherenkov telescopes at Ondrejov Observatory, Prague, Czech Republic. These telescopes operate in mono and stereoscopic modes, utilizing the Imaging Atmospheric Cherenkov Technique (IACT) to detect Very High Energy (VHE) gamma rays in the 1-300 TeV energy range. We present recent SST-1M observations, data analysis, and the results of preliminary physical modeling of Mrk 421's emission mechanisms.
