W2246, a Hot-DOG at z~4.6, is the most luminous object in the universe, powered by a powerful radio-quiet quasar. W2246 is a unique object in several ways. For example, previous studies have revealed that W2246 lives in an overdense environment, showing merger activity with at least three galaxies and also being associated with a highly turbulent interstellar medium (ISM). Through the MUSE observation of W2246, I intend to map the Lyma-alpha emission of the W2246 system. This will provide crucial insights into the role of environment, an understanding of the physical processes in W2246 system, feedback on the surrounding gas and dust, etc.<\/li>\n\n\n\n<li>The simulations predicted nearly half a million radio sources, with radio-loud AGNs in the dominant fraction, to be present at z&gt;4-7. This shows that there is a significant difference between the predicted number of radio sources at z&gt;4 and what previous studies have observed so far. Utilizing Lyman Dropout technique and the data from one of the deep radio continuum surveys, Evolutionary Map of the Universe (EMU), I have selected 990 candidates for the \u2018missing\u2019 radio population at z&gt;4-7. This sample revealed that \u2018missing\u2019 radio sources at z&gt;4 comprise a new class of low-luminosity (high-z) radio-loud AGNs. I intend to carry out spectroscopic and multifrequency radio observations of this sample, which is essential to confirm their redshifts and fully characterize the \u2018missing\u2019 radio population at z&gt;4.<\/li>\n<\/ul>\n\n\n\n<h5 class=\"wp-block-heading\">Highlights<\/h5>\n\n\n\n<ul>\n<li>ALMA-ANID funding (2023 \u2013 2025)<\/li>\n\n\n\n<li>Western Sydney University postgraduate research scholarship (2019 \u2013 2022)<\/li>\n\n\n\n<li>INSPIRE fellowship (2012 \u2013 2017)<\/li>\n\n\n\n<li>Member of EMU survey collaboration<\/li>\n\n\n\n<li>Member of HotDOG working group<\/li>\n<\/ul>\n\n\n\n<h5 class=\"wp-block-heading\">Publications<\/h5>\n\n\n\n<p><a href=\"https:\/\/orcid.org\/0000-0002-5033-8056\"><strong>ORCID<\/strong><\/a><\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Extracurricular activities<\/h5>\n\n\n\n<p>Hiking, travelling<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Contact me<\/h5>\n\n\n\n<p>devika.shobhana [at] mail.udp.cl<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Postdoctoral researcher, interested in the co-evolution of galaxies and AGN, particularly in luminous Hot-DOGs, radio galaxies, and Lyman Break Galaxies.<\/p>\n","protected":false},"author":4,"featured_media":5015,"menu_order":0,"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":"disabled","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":""},"researcher-category":[255],"acf":[],"_links":{"self":[{"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher\/5003"}],"collection":[{"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher"}],"about":[{"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/types\/researcher"}],"author":[{"embeddable":true,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/users\/4"}],"version-history":[{"count":9,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher\/5003\/revisions"}],"predecessor-version":[{"id":7833,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher\/5003\/revisions\/7833"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/media\/5015"}],"wp:attachment":[{"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/media?parent=5003"}],"wp:term":[{"taxonomy":"researcher-category","embeddable":true,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher-category?post=5003"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
