But how do these images connect to broader questions regarding the workings of accretion in general, or the launching of jets and particle acceleration, common to a wide variety of astrophysical phenomena?&nbsp; After a brief review of the Event Horizon Telescope (EHT) project and the current state-of-the-art, I will describe how these single-frequency imaging projects are starting to expand in several directions: &nbsp;frequency, dynamical range, size, timescale. I will also discuss how the combination of such images with multi-wavelength and multi-messenger data, together with recent advances in theoretical modelling, have the potential to tackle some of the hairiest problems relating to black holes and compact objects in general.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>AGN Santiago Club, talk by Dr. Sera Markoff (API\/GRAPPA, University of Amsterdam &amp; EHTC Science Board), November 13<\/p>","protected":false},"featured_media":8350,"template":"","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"site-sidebar-layout":"default","site-content-layout":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":""},"event-category":[263],"acf":[],"_links":{"self":[{"href":"https:\/\/astronomia.udp.cl\/es\/wp-json\/wp\/v2\/event\/8341"}],"collection":[{"href":"https:\/\/astronomia.udp.cl\/es\/wp-json\/wp\/v2\/event"}],"about":[{"href":"https:\/\/astronomia.udp.cl\/es\/wp-json\/wp\/v2\/types\/event"}],"version-history":[{"count":6,"href":"https:\/\/astronomia.udp.cl\/es\/wp-json\/wp\/v2\/event\/8341\/revisions"}],"predecessor-version":[{"id":8359,"href":"https:\/\/astronomia.udp.cl\/es\/wp-json\/wp\/v2\/event\/8341\/revisions\/8359"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/astronomia.udp.cl\/es\/wp-json\/wp\/v2\/media\/8350"}],"wp:attachment":[{"href":"https:\/\/astronomia.udp.cl\/es\/wp-json\/wp\/v2\/media?parent=8341"}],"wp:term":[{"taxonomy":"event-category","embeddable":true,"href":"https:\/\/astronomia.udp.cl\/es\/wp-json\/wp\/v2\/event-category?post=8341"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
