Organic compounds on comet 67P/Churyumov-Gerasimenko revealed by COSAC mass spectrometry
Fred Goesmann,H. Rosenbauer,Jan Hendrik Bredehöft,Michel Cabane,Pascale Ehrenfreund,Thomas Gautier,Chaitanya Giri,Chaitanya Giri,Harald Krüger,Léna Le Roy,A. J. MacDermott,Susan McKenna-Lawlor,Uwe J. Meierhenrich,Guillermo M. Muñoz Caro,François Raulin,Reinhard Roll,Andrew Steele,Harald Steininger,Robert Sternberg,Cyril Szopa,Wolfram Thiemann,Stephan Ulamec +21 more
TL;DR: The evolved gas analyzer Cometary Sampling and Composition experiment aboard Rosetta’s Philae lander was designed for in situ analysis of organic molecules on comet 67P/Churyumov-Gerasimenko, and displayed a suite of 16 organic compounds that had not previously been reported in comets.
Journal ArticleDOI
Photonenergy‐Controlled Symmetry Breaking with Circularly Polarized Light
Cornelia Meinert,Søren Vrønning Hoffmann,Patrick Cassam-Chenaï,Amanda C. Evans,Chaitanya Giri,Laurent Nahon,Uwe J. Meierhenrich +6 more
TL;DR: Stereocontrol provides novel insights into the wavelength and polarization dependence of asymmetric photochemical reactions and are highly relevant for absolute asymmetric molecular synthesis and for understanding the origins of homochirality in living matter.
Journal ArticleDOI
Chirality, photochemistry and the detection of amino acids in interstellar ice analogues and comets
TL;DR: The original life-generating, symmetry-breaking event is explored and recent thoughts on the origin of enantiomeric excess in the universe are summarised and the transfer of asymmetry from chiral photons to racemic amino acids is highlighted.
Journal ArticleDOI
Drainage systems of Lonar Crater, India: Contributions to Lonar Lake hydrology and crater degradation
Goro Komatsu,P. Senthil Kumar,Kazuhisa Goto,Kazuhisa Goto,Yasuhito Sekine,Chaitanya Giri,Takafumi Matsui +6 more
TL;DR: In this paper, the authors conducted a study of various drainage systems of Lonar Crater and found that the lake level is influenced by surface runoff that is active during the monsoon and groundwater input effective during both the rainy and the dry seasons.
Journal ArticleDOI
Simple prebiotic synthesis of high diversity dynamic combinatorial polyester libraries
Kuhan Chandru,Nicholas Guttenberg,Chaitanya Giri,Yayoi Hongo,Christopher J. Butch,Irena Mamajanov,H. James Cleaves +6 more
TL;DR: It is shown that alpha-hydroxy acids, which are plausibly abundant prebiotic monomers, can be oligomerized to generate vast, likely sequence-complete libraries, which is useful for scaffolding the origin of life.
