Formation and Growth of the First Supermassive Black Holes
Formation and Growth of the First Supermassive Black Holes Ph.D. Thesis by Tilman Hartwig UNIVERSITÉ PIERRE ET MARIE CURIE École Doctorale d’Astronomie et Astrophysique d’Île-de-France Ph.D. Thesis to obtain the title of Doctor in Astrophysics of the University Pierre et Marie Curie Presented by Tilman Hartwig Formation and Growth of the First Supermassive Black Holes Thesis Advisor: Dr. Marta Volonteri prepared at the Institut d’Astrophysique de Paris, CNRS (UMR 7095), Université Pierre et Marie Curie (Paris VI) with financial support from the European Research Council grant ‘BLACK’ Presented and publicly defended on the 22nd of September, 2017 to a jury consisting of Reviewers: Michela Mapelli - INAF, Padova, Italy Jarrett Johnson - LANL, Los Alamos, USA Advisor: Marta Volonteri - IAP, Paris, France President: Frédéric Daigne - IAP, Paris, France Examiner: Ralf Klessen - ZAH, Heidelberg, Germany Formation and Growth of the First Supermassive Black Holes Supermassive black holes reside in the centres of most massive galaxies and we observe correlations between their mass and properties of the host galaxies, such as bulge mass or stellar velocity dispersion. Besides this correlation between a galaxy and its central black hole (BH), we see BHs more massive than one billion solar masses already a few hundred million years after the Big Bang. These supermassive BHs at high redshift are just the tip of the iceberg of the entire BH population, but they challenge our understanding of the formation and growth of the first BHs. With this thesis, I contribute to a better understanding of the formation and growth of the first supermassive BHs with theoretical models and comparisons to recent observations. -

Dayananda G.Y. Abstract Department of P.G. Studies and The quantification of butterfly diversity and species richness is of core importance for evaluating the Research in Applied Zoology, Bio- status of protected areas. Gudavi bird sanctuary is one of the well known bird sanctuaries of Karnataka Sciences complex, Jnana and this area due to its geographical speciality evokes wide range of butterfly fauna, which plays a vital Sahyadri, Shankaraghatta -577 role in pollination of various flowering plants besides a key component of food chain. A total of 115 451. Shimoga. species representing 78 genera belonging to five families and 15 subfamilies were recorded in the present study. Of these, the family Nymphalidae was found to be the most dominant with 34.78% (40) species followed by Lycaenidae (25 species), Hesperiidae (18 species), Papilionidae and Pieridae (16 species). Large scale availability of larval hosts and adult nectar plants is the main reason for abundant diversity of butterflies in the region. Keywords: Butterfly fauna, diversity, Gudavi bird sanctuary, Karnataka, Sorab. 1. Introduction Butterflies are the potential umbrella group for biodiversity conservation. They are good subjects for dispersal studies and have enormous ecological importance. They serve as food for predators at various levels. The larvae, which feed on foliage, are primary herbivores in the ecosystem and are important in the transfer of energy fixed by plants, making them available to the other organisms in the ecosystem. -

Dragonflies & Butterflies of the Western Ghats Naturetrek Tour Report 7 - 16 September 2019 Ruby-tailed Hawklet Tamil Lacewing Gladeye Bushbrown Bonnet Macaque Report by David Raju Images courtesy of Paul Hanks Naturetrek Mingledown Barn Wolf's Lane Chawton Alton Hampshire GU34 3HJ UK T: +44 (0)1962 733051 E: [email protected] W: www.naturetrek.co.uk Tour Report Dragonflies & Butterflies of the Western Ghats Tour participants: David Raju (leader) with three Naturetrek clients Summary It was a wonderful eight-days trip to the Western Ghats to search for butterflies and dragonflies. We had a bit of rain at times but managed to see good butterflies and dragonflies with a few endemic ones. All the guests were keen on other wildlife, so we did some birding every morning and then looked for butterflies and dragonflies; after dinner we went out to look for amphibians and reptiles. We have managed to see 76 species of butterfly, plus some unidentified ones, and 47 species of dragonfly. During the trip we also managed to see Smooth-coated Otter, Jungle Palm (also known as Jungle Striped) Squirrel, Indian Giant Squirrel, Nilgiri (Dusky-striped) Palm Squirrel, Nilgiri Langur, Bonnet Macaque, Lesser Woolly Horseshoe Bat, Flying Foxes, Bengal (Indian) Monitor lizards, and a few rare species of geckos and frogs. In fact, it was turned out to be a very fruitful trip for biodiversity. Day 1 Saturday 7th September The group boarded their overnight flight to Kochi, via Dubai. Day 2 Sunday 8th September Nedumbassery Airport to Kumarakom (Coconut Lagoon) The group landed at Cochin International Airport, in Nedumbassery, and met with David, to start the adventure. -
8 October Version
A F irst T ransients Survey with JWST: the FLARE project Lifan Wang et al 8 October version Received ; accepted –2– ABSTRACT JWST was conceived and built to answer one of the most fundamental ques- tions that humans can address empirically: “How did the Universe make its first stars?”. This can be attempted in classical stare mode and by still photography - with all the pitfalls of crowding and multi-band redshifts of objects of which a spectrum was never obtained. Our First Lights At REionization (FLARE) project transforms the quest for the epoch of reionization from the static to the time domain. It targets the complementary question: “What happened to those first stars?”. It will be answered by observations of the most luminous events: supernovae and accretion on to black holes formed by direct collapse from the primordial gas clouds. These transients provide direct constraints on star-formation rates (SFRs) and the truly initial Initial Mass Function (IMF), and they may identify possible stellar seeds of supermassive black holes (SMBHs). Furthermore, our knowledge of the physics of these events at ultra-low metallic- ity will be much expanded. JWST’s unique capabilities will detect these most luminous and earliest cosmic messengers easily in fairly shallow observations. However, these events are very rare at the dawn of cosmic structure formation and so require large area coverage. Time domain astronomy can be advanced to an unprecedented depth by means of a shallow field of JWST reaching 27 mag AB in 2 µm and 4.4 µm over a field as large as 0.1 square degree visited multiple times each year. -
Baseline Metal Enrichment from Population III Star Formation in Cosmological Volume Simulations
MNRAS 000,1{ ?? (2017) Preprint 19 January 2018 Compiled using MNRAS LATEX style file v3.0 Baseline Metal Enrichment from Population III Star Formation in Cosmological Volume Simulations Jason Jaacks1?, Robert Thompson2;3, Steven L. Finkelstein1 and Volker Bromm1 1 Department of Astronomy, The University of Texas at Austin, Austin, TX 78712 2 Portalarium Inc., Austin, TX 78731 3 National Center for Supercomputing Applications, University of Illinois at Urbana-Champaign, Champaign, IL 61801 Accepted XXX. Received YYY; in original form ZZZ ABSTRACT We utilize the hydrodynamic and N-body code GIZMO coupled with our newly devel- oped sub-grid Population III (Pop III) Legacy model, designed specifically for cosmo- logical volume simulations, to study the baseline metal enrichment from Pop III star formation at z > 7. In this idealized numerical experiment, we only consider Pop III star formation. We find that our model Pop III star formation rate density (SFRD), −3 −1 −1 which peaks at ∼ 10 M yr Mpc near z ∼ 10, agrees well with previous numerical studies and is consistent with the observed estimates for Pop II SFRDs. The mean Pop III metallicity rises smoothly from z = 25 − 7, but does not reach the critical −4 metallicity value, Zcrit = 10 Z , required for the Pop III to Pop II transition in star formation mode until z ' 7. This suggests that, while individual halos can suppress in-situ Pop III star formation, the external enrichment is insufficient to globally ter- minate Pop III star formation. The maximum enrichment from Pop III star formation −2 in star forming dark matter halos is Z ∼ 10 Z , whereas the minimum found in −7 externally enriched haloes is Z & 10 Z . -

Previous stud- ies suggest that CR7 hosts either young primordial stars with a total stellar mass of 7 6 ∼ 10 M⊙ or a black hole of & 10 M⊙. Here, we explore different formation scenarios for CR7 with a semianalytical model, based on the random sampling of dark matter merger trees. We are unable to reproduce the observational constraints with a primor- dial stellar source, given our model assumptions, due to the short stellar lifetimes and the early metal enrichment. Black holes that are the remnants of the first stars are either not massive enough, or reside in metal-polluted haloes, ruling out this possible explanation of CR7.
