15 صفحه اولThe Linear Polarization of Sagittarius A * II
We present a search for linear polarization at 22 GHz, 43 GHz and 86 GHz from the nearest super massive black hole candidate, Sagittarius A*. We nd upper limits to the linear polarization of 0.2%, 0.4% and 1%, respectively. These results strongly support the conclusion of our centimeter wavelength spectro-polarimetry that Sgr A* is not depolarized by the interstellar medium but is in fact intri...
متن کاملOn the Linear Polarization Constant Of
The present work contributes to the determination of the n-th linear polarization constant cn(H) of an n-dimensional real Hilbert space H . We provide some new lower bounds on the value of sup‖y‖=1 | 〈x1, y〉 · · · 〈xn, y〉 |, where x1, . . . , xn are unit vectors in H . In particular, the results improve an earlier estimate of Marcus. However, the intriguing conjecture cn(H) = n n/2 remains open...
متن کاملThe Linear Polarization of Sagittarius A
Synchrotron radiation from active galactic nuclei (AGN) is often highly polarized. We present a search for linear polarization with the Very Large Array (VLA) at 4.8 GHz and 8.4 GHz from the nearest AGN, Sagittarius A*. As a part of this study we used spectro-polarimetric data that were sensitive to a rotation measure (RM) as large as 3:5 10 6 rad m ?2 at 4.8 GHz and 1:5 10 7 rad m ?2 at 8.4 GH...
متن کاملThe dth linear polarization constant of Rd
In [C. Benítez, Y. Sarantopoulos, A. Tonge, Lower bounds for norms of products of polynomials, Math. Proc. Cambridge Philos. Soc. 124 (3) (1998) 395–408] it was conjectured that for all unit vectors u1, . . . , ud in Rd , X (u1, . . . , ud ) := sup x∈Rd , |x|2=d d ∏ i=1 〈x,ui〉 1 with equality occurring iff u1, . . . , ud are orthonormal. We relate this to a conjecture about solutions of Ay = y−...
