astro-ph0302044 | ground - based 2.84.1 @xmath0 m slit spectra of the nuclei of seven ultraluminous infrared galaxies ( ulirgs ) that are classified optically as liners and have cool far - infrared colors are presented . all the nuclei show 3.3 @xmath0 m polycyclic aromatic hydrocarbon ( pah ) emission , with equivalent widths that are ... | 262 |
gr-qc0311018 | an approximate analytical and non - linear solution of the einstein field equations is derived for a system of multiple non - rotating black holes . the associated space - time has the same asymptotic structure as the brill - lindquist initial data solution for multiple black holes . the system admits an arnowitt - des... | 297 |
1703.09974 | the effect of monolayers of oxygen ( o ) and hydrogen ( h ) on the possibility of material transfer at aluminum / titanium nitride ( al / tin ) and copper / diamond ( cu / c@xmath0 ) interfaces , respectively , were investigated within the framework of density functional theory ( dft ) . to this end the approach , cont... | 201 |
