In poetry:
I must not heed that elemental Whirl
Where Arc on Arc the trainèd Planets swirl -
The Astronomic Marvels have no charm
For him who walks the Gloaming with his Girl.
"The Rubáiyát of Omar Khayyám Jr." by Wallace Irwin
So take our thanks, dear reader of the skies,
Devout astronomer, most humbly wise,
For lessons brighter than the stars can give,
And inward light that helps us all to live.

Once on a time the astronomers foresaw
The coming of a star to madden men:
Thus warned they fled the land, thinking that when
The folk were crazed, they'd hold the reins of law
"Sonnet XII." by Tommaso Campanella
Then add to these the bard who tamed
The monsters of the flood;
And with his oaten reed reclaim'd For by th' initials will be shown
A planet all serene,
Which to astronomers is known
By the name of heaven's queen.
"Enigma XIII." by Elizabeth Hitchener
Till broken in the shift of quieter
Dense altitudes tangential of your steel,
I am become geometries, and glut
Expansions like a blind astronomer
Dazed, while the worldless heavens bulge and reel
In the cold revery of an idiot.

In science:
This property makes much more diﬃcult any direct detection of gravitational waves by astronomical techniques if general relativity is correct.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
Any astronomical observation is done with electromagnetic waves (photons) of different frequencies with an overall spectrum spreading out from radio waves to gamma rays.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
In the present paper we consider a general case of an asymptotically-ﬂat space-time to which an isolated astronomical system is embedded.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
Linearized approximation of general theory of relativity represents a straightforward approach for description of the multipolar structure of the gravitational ﬁeld of a localized astronomical system.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
Photon propagates through the time-dependent gravitational ﬁeld of an isolated astronomical system emitting gravitational waves.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
Observing these changes allow us to study properties of the gravitational ﬁeld of the astronomical system and to detect gravitational waves with astronomical technique.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
However, continually growing accuracy of astronomical observations demands much better treatment of secondary effects in the propagation of light produced by the perturbations of the gravitational ﬁeld associated with higher-order gravitational multipoles.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
Calculation of these perturbations is important for developing correct strategy for searching gravitational waves by making use of astronomical technique.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
We consider an isolated astronomical system emitting gravitational waves and assume that gravitational ﬁeld is weak everywhere so that the metric tensor is expanded in a Taylor series with respect to the powers of gravitational constant G.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
For computational convenience and simpliﬁcation of physical interpretation of our results, we put the origin of the coordinate system to the center of mass of the isolated astronomical system under consideration .
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
The most general expression for the linearized perturbation of the metric tensor outside of the astronomical system under consideration was given by Thorne (see also ) in terms of its symmetric and trace-free (STF) mass and spin multipole moments.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
We emphasize that in the linearized approximation the total mass M and spin Si of the astronomical system are considered as constant while all other multipoles are arbitrary functions of time.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
At the same time freely-falling observers experience inﬂuence of gravitational waves emitted by the isolated astronomical system and move with respect to the canonical harmonic coordinate system in a complicated way.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
Making use of the canonical ADM coordinates simpliﬁes analysis of the gravitational wave effects observed at gravitational wave observatories (LIGO, LISA) or by astronomical technique because the motion of observer (proof mass) is excluded from the equations.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
It can be shown that the expansion ϑ of the light-ray congruence is deﬁned by the stationary components of the gravitational ﬁeld of the isolated astronomical system determined by its mass M, and spin S i , and does not depend on higher-order multipole moments.
