This paper, the first in the Galactic Energy Profiles series, introduces a reproducible geometric framework for accounting radiant and relativistic fluxes as a standing energy reservoir. By considering the photon and neutrino escape time \u03c4 across the galactic Halo, we quantify the energy density of radiation currently in transit as a component of the total galactic budget, complementary to the standard flux-based description. The resulting closed-form expressions, together with the accompanying open-source Python implementation, are intended as a calibrated methodological baseline for the subsequent application of this framework to observed galactic samples.<\/p>\n<p>Keywords<br \/>\ngalactic energy inventory; energy residence time; galactic radiant fluxes; galactic Halo energy; galaxy morphology<\/p>\n<hr \/>\n<p>Here is the Zenodo version of the paper (1.1 MB):<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-2140\" src=\"https:\/\/andreabrussi.it\/wp-content\/uploads\/link.png\" alt=\"pdf\" width=\"25\" height=\"30\" \/> <a href=\"https:\/\/doi.org\/10.5281\/zenodo.22009753\" target=\"_blank\" rel=\"noopener\">Brussi 2026 GEP I<\/a><\/p>\n<hr \/>\n<p><a href=\"https:\/\/andreabrussi.it\/wp-content\/uploads\/GEP-I-mean-escape-trajectory-length.png\" rel=\"lightbox[2523]\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-3253 size-medium\" src=\"https:\/\/andreabrussi.it\/wp-content\/uploads\/GEP-I-mean-escape-trajectory-length-300x197.png\" alt=\"GEP I mean escape trajectory length\" width=\"300\" height=\"197\" srcset=\"https:\/\/andreabrussi.it\/wp-content\/uploads\/GEP-I-mean-escape-trajectory-length-300x197.png 300w, https:\/\/andreabrussi.it\/wp-content\/uploads\/GEP-I-mean-escape-trajectory-length-768x504.png 768w, https:\/\/andreabrussi.it\/wp-content\/uploads\/GEP-I-mean-escape-trajectory-length.png 988w\" sizes=\"auto, (max-width: 300px) 85vw, 300px\" \/><\/a><\/p>\n<div style='text-align:right' class='yasr-auto-insert-visitor'><!--Yasr Visitor Votes Shortcode--><div id='yasr_visitor_votes_65aa92ebc2a9c' class='yasr-visitor-votes'><div class=\"yasr-custom-text-vv-before yasr-custom-text-vv-before-2517\">please, rate this post<\/div><div id='yasr-vv-second-row-container-65aa92ebc2a9c'\r\n                                        class='yasr-vv-second-row-container'><div id='yasr-visitor-votes-rater-65aa92ebc2a9c'\r\n                                      class='yasr-rater-stars-vv'\r\n                                      data-rater-postid='2517'\r\n                                      data-rating='0'\r\n                                      data-rater-starsize='16'\r\n                                      data-rater-readonly='false'\r\n                                      data-rater-nonce='4bc8a13a69'\r\n                                      data-issingular='false'\r\n                                    ><\/div><div class=\"yasr-vv-stats-text-container\" id=\"yasr-vv-stats-text-container-65aa92ebc2a9c\"><svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" width=\"20\" height=\"20\"\r\n                                   class=\"yasr-dashicons-visitor-stats\"\r\n                                   data-postid=\"2517\"\r\n                                   id=\"yasr-stats-dashicon-65aa92ebc2a9c\">\r\n                                   <path d=\"M18 18v-16h-4v16h4zM12 18v-11h-4v11h4zM6 18v-8h-4v8h4z\"><\/path>\r\n                               <\/svg><span id=\"yasr-vv-text-container-65aa92ebc2a9c\" class=\"yasr-vv-text-container\"><\/span><\/div><div id='yasr-vv-loader-65aa92ebc2a9c' class='yasr-vv-container-loader'><\/div><\/div><div id='yasr-vv-bottom-container-65aa92ebc2a9c'\r\n                              class='yasr-vv-bottom-container'\r\n                              style='display:none'><\/div><\/div><!--End Yasr Visitor Votes Shortcode--><\/div>","protected":false},"excerpt":{"rendered":"<p>Galactic Energy Profiles: GEP I.
