Kinematic Lie Algebras From Twistor Spaces
(2023-07-28)We analyze theories with color-kinematics duality from an algebraic perspective and find that any suchtheory has an underlying BV▪-algebra, extending the ideas of Reiterer [A homotopy BV algebra for Yang–Mills and ... -
Kinematic Lie Algebras From Twistor Spaces
(2023-07-28)We analyze theories with color-kinematics duality from an algebraic perspective and find that any such theory has an underlying BV${}^{\color{gray} \blacksquare}$-algebra structure, extending the ideas of arXiv:1912.03110. ... -
The kinematic signature of the Galactic warp in Gaia DR1 : I. the H ipparcos subsample
(2017-05-15)Context. The mechanism responsible for the warp of our Galaxy, as well as its dynamical nature, continues to remain unknown. With the advent of high precision astrometry, new horizons have been opened for detecting the ... -
A kinematically distinct core and minor-axis rotation : the MUSE perspective on M87
(2014-11-21)We present evidence for the presence of a low-amplitude kinematically distinct component in the giant early-type galaxy M87, via data sets obtained with the SAURON and MUSE integral-field spectroscopic units. The MUSE ... -
The kinematics and the origin of the ionized gas in NGC 4036
(1999)We present the kinematics and photometry of the stars and of the ionized gas near the centre of the S0 galaxy NGC4036. Dynamical models based on the Jeans Equation have been constructed from the stellar data to determine ... -
Kinematics in the central kiloparsec of spiral galaxies
(Astronomical Society of the Pacific, 2001)Results from kinematic observations of the central regions of spiral galaxies are reviewed, with particular emphasis on starburst and AGN hosts. While morphological studies lead to important insights, a more complete ... -
The kinematics of Core and Cusp galaxies : comparing HST imaging and integral-field observations
(Springer Nature, 2010)In this proceeding we look at the relationship between the photometric nuclear properties of early-type galaxies from Hubble Space Telescope imaging and their overall kinematics as observed with the SAURON integral-field ... -
Kinematics of massive star ejecta in the Milky Way as traced by $^26$Al
(2013-11-19)Context. Massive stars form in groups and their winds and supernova explosions create superbubbles up to kpc in size. The fate of their ejecta is of vital importance for the dynamics of the interstellar medium, for chemical ... -
Kinematics of the Circumnuclear Region of M 100
(Astronomical Society of the Pacific, 2000)Circumnuclear regions of barred galaxies can host ring-like regions of enhanced star formation, thought to be related to the position of one or more Inner Lindblad resonance(s). Here we present kinematic observations and ... -
Kinematics of the parsec-scale radio jet in 3C 48
(2010)We present results on the compact steep-spectrum quasar 3C 48 from observations with the Very Long Baseline Array (VLBA), the Multi-Element Radio Linked Interferometer Network (MERLIN) and the European Very long baseline ... -
Kinematics, Structure, and Mass Outflow Rates of Extreme Starburst Galactic Outflows
(2023-05-19)We present results on the properties of extreme gas outflows in massive (M * ∼ 1011 M ⊙), compact, starburst (star formation rate, SFR∼ 200 M ⊙ yr−1) galaxies at z = 0.4–0.7 with very high star formation surface densities ... -
Kinetic analysis of the induction period in lipoxygenase catalysis
(1993)The dioxygenation of 50 pM linoleate at 0.1 pM (13s)-hydroperoxylinoleate, 240 pM 02, pH 10, and 25 O C , catalyzed by varying amounts of soybean lipoxygenase-1, was studied with rapid kinetic techniques. The aim was to ... -
Kinetic dissociation of nickel titanate and nickel tungstate in oxygen potential gradients
(1994-06-01)Nickel titanate (NiTiO) and nickel tungstate (NiWO) were exposed to oxygen potential gradients at 1400 and 1100° C, and they were found to dissociate into their constituent oxides, namely, NiO and TiO, and WO and NiO, ... -
Kiss, don’t tell: attitudes towards inter-ethnic dating and contact with the Other in Bosnia-Herzegovina
(2022-10-21)Structural segregation and normative divisions in Bosnia-Herzegovina make dating across ethnic lines difficult. A detailed and rich scholarship outlines why this is and why young people who want to interact across ethnic ... -

A kitchen-based intervention to improve nutritional intake from school lunches in children aged 12-16 years
(2013-06)Background: School lunches potentially provide an important source of nutrients for children but studies have shown that their food choices are not always associated with health benefits. This study aimed to evaluate the ... -
Kleiss-Kuijf relations from momentum amplituhedron geometry
(2021-07-16)Abstract: In recent years, it has been understood that color-ordered scattering amplitudes can be encoded as logarithmic differential forms on positive geometries. In particular, amplitudes in maximally supersymmetric ... -
The KLEVER survey: nitrogen abundances at z ∼ 2 and probing the existence of a fundamental nitrogen relation
(2022-05-30)We present a comparison of the nitrogen-to-oxygen ratio (N/O) in 37 high-redshift galaxies at z ∼2 taken from the KMOS Lensed Emission Lines and VElocity Review (KLEVER) Survey with a comparison sample of local galaxies, ...
