This generalization could potentially result in observable effects even below the Planck energy scale, offering an opportunity to investigate quantum gravity theories through physical processes at lower energy scale. In this paper, we study, within the framework of the DDC formalism, the effect of GUP on the spontaneous excitation and de-excitation of a multilevel atom in both inertial and non-inertial motions coupled to a vacuum electromagnetic field. The GUP modifies the two point function of the electromagnetic field, thereby affecting the radiative properties of atom. We show that the GUP can alter the rate of change of mean atomic energy, resulting in either an enhancement or a reduction, depending on the sign of the GUP parameter <em>β</em>.

As a modified gravity model that potentially explains the dynamics of spiral galaxies and dark matter effects, Rindler acceleration demonstrates significant implications for black hole physics research. Utilizing EHT observational data, we model the supermassive black holes M87* and Sgr A* as Rindler-accelerated black holes, thereby constraining the Rindler acceleration parameter and establishing more observationally plausible models. Building upon this foundation and incorporating the GLM accretion disk model, we examine the influence of Rindler acceleration on black hole shadows as well as bright rings. The results show that as Rindler acceleration increases, the black hole shadow radius decreases and corresponding brightness of the ring intensifies. Furthermore, by constructing highly blurred images that approximate EHT observations, we demonstrate the characteristics of direct image, lensing ring and photon ring under various configurations of the GLM model. The results indicate that variations in both the accretion disk and Rindler acceleration can generate distinct shadow images and optical appearances. Within the current precision limits of EHT data, our analysis suggests the potential for M87* and Sgr A* to be Rindler-accelerated black holes.</div></div>","PeriodicalId":20162,"journal":{"name":"Physics Letters B","volume":"868 ","pages":"Article 139782"},"PeriodicalIF":4.5,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144781332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
